downwards from the posterior axillary fold

bull Midaxillary Line- Runs vertically downward from a point situated midway between the anterior and posterior folds

bull Scapular Line- Runs vertically downward on the posterior wall of the thorax passing through the inferior angle of the scapula (arms at sides)

bull Nipple (in males)-lies in the 4th intercostal space about 10 cm from midline

bull Apex Beat- in 5th intercostal space 9cm from midline (just below and medial to the nipple) Marks the lowest and outermost point at which the cardiac impulse can be palpated

bull Transpyloric Plane (of Addison)- Lies halfway between the suprasternal notch and pubis or approx one hands breadth below the xiphoid (L1 Level)

passes through the Pylorus the pancreatic neck the duodenojejunal flexure the fundus of the gall bladder the tip of the 9th costal cartilage and hila of the kidneys

Also corresponds to the level of termination of the Spinal Cord

bull Subcostal Plane- L3 Line joining the lowest point of the thoracic

cage on each side (inferior margin of the 10th rib)- passes through the origin of the inferior mesenteric artery

The Anterior Region of the Neck

bull Has several palpable landmarks including the larynx trachea and sternal notch

bull The larynx ndash found in the middle of the neck ndash composed of multiple cartilages ndash thyroid cartilage

bull ldquoAdamrsquos applerdquo bull Inferior to the larynx are the cricoid cartilage and trachea bull Terminates at the sternal (jugular) notch of the manubrium and the

left and right clavicles

The Nuchal Region

bull The posterior neck region bull Houses the spinal cord cervical vertebrae and associated

structuresbull The bump at the lower boundary of this region is the vertebra

prominens

bull Superiorly along the midline of the neck is the ligamentum nuchae a thick ligament that runs from C7 to the nuchal lines of the skull

Left and Right Lateral Portions of the Neck

bull Contain the sternocleidomastoid muscles which partitions the neck into two clinically important triangles an anterior triangle and a posterior triangle

bull Each triangle houses important structures that run through the neck bull Triangles are further subdivided into smaller trianglesbull Anterior triangle lies anterior to the sternocleidomastoid muscle and

Gluteal Region

bull The inferior border of the gluteus maximus muscle forms the gluteal fold

bull The gluteal (natal) cleft extends vertically to separate the buttocks into two prominences

bull In the inferior portion of each buttock an ischial tuberosity can be palpated these tuberosities support body weight while seated

bull The gluteus maximus muscle forms most of the inferolateral ldquofleshyrdquo part of the buttock

bull The gluteus medius muscle may be palpated only in the superolateral portion of each buttock

The Thigh

bull Many muscular and bony features are readily identified in the thigh which extends between the hip and the knee on each lower limb

bull An extremely important element of thigh surface anatomy is a region called the femoral triangle

bull The femoral triangle is a depression inferior to the groove that overlies the inguinal ligament on the anteromedial surface in the superior portion of the thigh

bull The femoral artery vein and nerve travel through this region making it an important arterial pressure point for controlling lower limb hemorrhage

Thigh and Knee

bull On the distal part of the anterior thigh are the three parts of the quadriceps femoris as they approach the knee

bull Still on the anterior side of the thigh three obvious skeletal features can be observed and palpated ndash (1) The greater trochanter is palpated on the superior

lateral surface of the thigh ndash (2) the patella is located easily within the patellar

tendon and ndash (3) the lateral and medial condyles of both the femur

and tibia are identified and palpated at each knee

bull Many muscular and bony features are readily identified in the thigh which extends between the hip and the knee on each lower limb

bull An extremely important element of thigh surface anatomy is a region called the femoral triangle

bull The femoral triangle is a depression inferior to the groove that overlies the inguinal ligament on the anteromedial surface in the superior portion of the thigh

bull The femoral artery vein and nerve travel through this region making it an important arterial pressure point for controlling lower limb hemorrhage

Thigh and Knee

bull On the distal part of the anterior thigh are the three parts of the quadriceps femoris as they approach the knee

bull Still on the anterior side of the thigh three obvious skeletal features can be observed and palpated ndash (1) The greater trochanter is palpated on the superior

lateral surface of the thigh ndash (2) the patella is located easily within the patellar

tendon and ndash (3) the lateral and medial condyles of both the femur

and tibia are identified and palpated at each knee

Gluteal Region

bull The inferior border of the gluteus maximus muscle forms the gluteal fold

bull The gluteal (natal) cleft extends vertically to separate the buttocks into two prominences

bull In the inferior portion of each buttock an ischial tuberosity can be palpated these tuberosities support body weight while seated

bull The gluteus maximus muscle forms most of the inferolateral ldquofleshyrdquo part of the buttock

bull The gluteus medius muscle may be palpated only in the superolateral portion of each buttock

bull Many muscular and bony features are readily identified in the thigh which extends between the hip and the knee on each lower limb

bull An extremely important element of thigh surface anatomy is a region called the femoral triangle

bull The femoral triangle is a depression inferior to the groove that overlies the inguinal ligament on the anteromedial surface in the superior portion of the thigh

bull The femoral artery vein and nerve travel through this region making it an important arterial pressure point for controlling lower limb hemorrhage

Thigh and Knee

bull On the distal part of the anterior thigh are the three parts of the quadriceps femoris as they approach the knee

bull Still on the anterior side of the thigh three obvious skeletal features can be observed and palpated ndash (1) The greater trochanter is palpated on the superior

lateral surface of the thigh ndash (2) the patella is located easily within the patellar

tendon and ndash (3) the lateral and medial condyles of both the femur

The Nuchal Region

bull The posterior neck region bull Houses the spinal cord cervical vertebrae and associated

structuresbull The bump at the lower boundary of this region is the vertebra

prominens

bull Superiorly along the midline of the neck is the ligamentum nuchae a thick ligament that runs from C7 to the nuchal lines of the skull

Left and Right Lateral Portions of the Neck

bull Contain the sternocleidomastoid muscles which partitions the neck into two clinically important triangles an anterior triangle and a posterior triangle

bull Each triangle houses important structures that run through the neck bull Triangles are further subdivided into smaller trianglesbull Anterior triangle lies anterior to the sternocleidomastoid muscle and

inferior to the mandible ndash subdivided into four smaller triangles

bull the submental submandibular carotid and muscular triangles

The Posterior Triangle

bull Lateral region of the neckbull Posterior to the sternocleidomastoid musclebull Superior to the clavicle inferiorlybull Anterior to the trapezius muscle bull Subdivided into two smaller triangles

Gluteal Region

bull The inferior border of the gluteus maximus muscle forms the gluteal fold

bull The gluteal (natal) cleft extends vertically to separate the buttocks into two prominences

bull In the inferior portion of each buttock an ischial tuberosity can be palpated these tuberosities support body weight while seated

bull The gluteus maximus muscle forms most of the inferolateral ldquofleshyrdquo part of the buttock

bull The gluteus medius muscle may be palpated only in the superolateral portion of each buttock

The Thigh

bull Many muscular and bony features are readily identified in the thigh which extends between the hip and the knee on each lower limb

bull An extremely important element of thigh surface anatomy is a region called the femoral triangle

bull The femoral triangle is a depression inferior to the groove that overlies the inguinal ligament on the anteromedial surface in the superior portion of the thigh

bull The femoral artery vein and nerve travel through this region making it an important arterial pressure point for controlling lower limb hemorrhage

Thigh and Knee

bull On the distal part of the anterior thigh are the three parts of the quadriceps femoris as they approach the knee

bull Still on the anterior side of the thigh three obvious skeletal features can be observed and palpated ndash (1) The greater trochanter is palpated on the superior

lateral surface of the thigh ndash (2) the patella is located easily within the patellar

tendon and ndash (3) the lateral and medial condyles of both the femur

and tibia are identified and palpated at each knee

Gluteal Region

bull The inferior border of the gluteus maximus muscle forms the gluteal fold

bull The gluteal (natal) cleft extends vertically to separate the buttocks into two prominences

bull In the inferior portion of each buttock an ischial tuberosity can be palpated these tuberosities support body weight while seated

bull The gluteus maximus muscle forms most of the inferolateral ldquofleshyrdquo part of the buttock

bull The gluteus medius muscle may be palpated only in the superolateral portion of each buttock

The Thigh

bull Many muscular and bony features are readily identified in the thigh which extends between the hip and the knee on each lower limb

bull An extremely important element of thigh surface anatomy is a region called the femoral triangle

bull The femoral triangle is a depression inferior to the groove that overlies the inguinal ligament on the anteromedial surface in the superior portion of the thigh

bull The femoral artery vein and nerve travel through this region making it an important arterial pressure point for controlling lower limb hemorrhage

The Thigh

bull Many muscular and bony features are readily identified in the thigh which extends between the hip and the knee on each lower limb

bull An extremely important element of thigh surface anatomy is a region called the femoral triangle

bull The femoral triangle is a depression inferior to the groove that overlies the inguinal ligament on the anteromedial surface in the superior portion of the thigh

bull The femoral artery vein and nerve travel through this region making it an important arterial pressure point for controlling lower limb hemorrhage

Thigh and Knee

bull On the distal part of the anterior thigh are the three parts of the quadriceps femoris as they approach the knee

bull Still on the anterior side of the thigh three obvious skeletal features can be observed and palpated ndash (1) The greater trochanter is palpated on the superior

lateral surface of the thigh ndash (2) the patella is located easily within the patellar

tendon and ndash (3) the lateral and medial condyles of both the femur

and tibia are identified and palpated at each knee
