Skeletal & Muscle Unit
How many bones does the human skeleton contain?
Functions of the skeletal systemGive shape & support Protect internal organs Moves muscles Form blood cells Store calcium and phosphorous
Bone Cross Section Marrow: manufactures red blood cellsPeriosteum: soft, thin, covers and protects the bone Compact Bone: Hard, outer surface. Can heal itself when broken Spongy Bone: Porous, contains blood vessels, nerves Marrow: manufactures red blood cells
Skeletal System is divided into two parts
Axial Skeleton Skull (protects the brain).Ribs ( protect lungs, and heart). Spinal column (houses and protects the spinal cord).
Appendicular SkeletonLegs Pelvis Arms Shoulders
Types of Joints Immovable Movable Skull Pelvis Pivot Ball & socketHinge Gliding
Ball & Socket: Shoulders and HipsAllows arms and hips to move in any direction Can move in a full 360 degrees
Pivot Joints: First two neck vertebrae & joint beneath elbowMoves in a semicircle motion by twisting against each other
Hinged: Elbows & Knees Move like hinges on a door Limited movementCan only swing back and forth
Gliding Joints: Spine, Wrists, AnklesSlide against each other in a gliding motion Gives your wrists and ankles lots of freedom
Immoveable joints are located in the:

Skeletal System Bone formation: bones start as cartilage and slowly it is replaced by bone.

The Skeletal System.
The Skeletal System Skeleton composed of many different tissues: cartilage, bone tissue, epithelium, nerve, blood forming tissue, adipose, and dense connective.
THE SKELETAL SYSTEM.
Bones & Muscles. How many bones does the human skeleton contain?
Bones - the organs of the skeletal system.
Health Mrs. Wagner. Support your body Give it shape Work with muscles so you can move Bones – store important minerals and release them to the.
The Skeletal System. The human skeleton is an endoskeleton of bone and cartilage. Major Functions Support for the soft tissues and largely responsible.
Types of Joints Fibrous Fibrous joints connect bones without allowing any movement. The bones of your skull and pelvis are held together by fibrous joints.
The Skeletal System The skeletal system is the framework of your body and has 5 major functions:
