Study Notes

Skeletal System

Provides essential functions: support, protection, and movement.
Composed of both hard and flexible structures.

Bone

Hard tissue primarily made of cells, collagen, and calcium.

Joint

The point where two or more bones meet, enabling movement.

Cartilage

Strong yet flexible and elastic tissue that reduces friction between bones and increases flexibility during movement.

Muscle

Tissue comprised of long cells that have the ability to contract.

Contraction

A process where muscle filaments move closer together, resulting in muscle shortening.

Relaxation

A process where muscle filaments move away from each other, resulting in lengthening.

Tendon

Connective tissue that links muscles to bones, facilitating movement.

Cardiac Muscle

Specialized muscle found only in the heart, functioning involuntarily.

Smooth Muscle

Muscle type located in the lining of inner organs; also involuntary.

Skeletal Muscle

Muscle that attaches to bones, enabling voluntary movements of the skeleton.

Number of Bones

Infants have over 300 bones; adults typically have 206 as some bones fuse during growth.

Endoskeleton

An internal skeletal structure made of bone or cartilage, which grows with the organism.

Bone Marrow

Tissue found inside bones responsible for producing red and white blood cells.

Extension

The action of straightening a limb, increasing the angle between the bones of the limb.

Flexion

The bending of a limb, decreasing the angle between the bones.

Types of Joints

Gliding Joint: Enables bending and twisting movements (e.g., ankle, wrist, vertebrae).
Pivot Joint: Allows side-to-side and up-and-down movements (e.g., base of skull).
Hinge Joint: Facilitates back-and-forth movements (e.g., fingers, elbows, knees).
Ball and Socket Joint: Provides multi-directional movement and rotation (e.g., shoulders, hips).
Immovable Joint: Allows very limited or no movement (e.g., skull).
