Skeletal Research


SECTION 1

Parts of the Skeletal System Bone:Bones provide framework for the body. Bones protect vital organs from in-jury, an example of this would be the rib cage. They also store important minerals and produce blood.

Cartilage:Cartilage allows more movement and it is not as rigid as bone. It is found in joints between bones.

Ligaments and Tendons:Ligaments and tendons are soft tissues that connect different parts of the skeletal system to each other. Ligaments connect bone to bone, while ten-dons connect muscle to bone.

Joints: A joint is where two bones meet. They allow for movement.

Functions of the Skeletal System:-support-movement-protection-production of blood cells-storage of minerals-endocrine regulation

PARTS OF A BONE

There are 2 different types of bone, spongy and compact:

-Compact bones are the densely packed outer part of a bone

-Spongy bone is on the inside of the bone, it is weaker and it is where marrow is found.

Bone Marrow:

-It is a flexible tissue within bones. Bone marrow produces red blood cells in a process known as hematopoiesis.

Different Types of Joints:

Ball and Socket Joints:

Allows freedom of movement in all di-rections. Example: hip joint.

Hinge Joints:

One bone fits into the concave of an-other bone. Example:elbow

Gliding Joints:

Surfaces slide over one another, limited movement. Example: wrist


5

Pivot Joints:

A ring of bone rotates around another bone.Example: the palm of the hand

Compound Joints:

This joint is made up of sev-eral joints between different bones. This allows for more movement. Example: neck
