ENDOCRINE SYSTEM

The endocrine system controls your mood, sleep, hunger, digestion, emotions, breathing rate and the rate our heart beats just to name a few.

So how could one system have so much influence?

HORMONES

ENDOCRINE SYSTEM

• The major organs of the Endocrine system are glands– Hypothalamus– Thyroid– Pancreas– ovaries/testies– Pituitary gland– Parathyroid– Thymus– Adrenal Glands

• The functions of the Endocrine system are regulating your mood, growth and development, tissue function, and metabolism, as well as sexual function and reproductive processes.

Integumentary System

$5 Integument…..aka….”Cover”

--The integumentary system is composed of the skin, nails and glands.

Function of skin:1. Protection 2. Regulate body temperature3. Sensory

Integumentary System

Skin has 3 layers:1. Epidermis – nails and hair

2. Dermis – blood vessels, nerves, glands, smooth muscle, and hair

3. Hypodermis – fat

Types of Joints

Joints are found where two or more bones come together.

1. Ball and Socket – shoulder and hip

2. Hinge – elbow and knee

3. Gliding – wrist and ankle

4. Fixed – cranium (sutures)

5. Pivot – head atop the vertebrae

Knee bone is connected by the…

• Cartilage – cushions the bones

• Tendons – muscle to bone

• Ligament – bone to bone
