1. The human skeleton consists of 206 bones
3. Bones manufacture blood cells and store important minerals.
4. The longest bone in our body is the femur (thigh bone), While The smallest bone is the stirrup bone.
5. Each hand has 26 bones in it.
1. Contains 80 bones.
2. It is composed of six parts
3. FOUND ALONG THE CENTRAL AXIS OF THE BODY.
The sacrum is a triangular bone located at the bottom of the spine. Because of its position between the 2 hip bones, the sacrum functions as a keystone (or wedge), stabilizing the bony pelvis.
the vertebrae protects the spinal chord, provides support to the body as a whole, and serves as a place to which the pectoral and pelvic girdles as well as many muscles attach
The coccyxhelps you sit down comfortably by providing a third point of impact and lots of muscles and tendons attach to it such as those controlling your pelvic floor muscles which help you know when to go to the toilet and those that help you walk like your butt muscle (gluteus maximus).
1. The appendicularskeleton protects the organs of digestion, excretion and reproduction.
2. called appendicular (from "append") because they are attached by girdles, which bridge each with the main body, as if they had been appended after the main body was formed
The human shoulder is made up of three bones: the clavicle(collarbone), the scapula(shoulder blade), and the humerus (upper arm bone) as well as associated muscles, ligaments and tendons. The articulations between the bones of the shoulder make up the shoulder Joints. The major joint of the shoulder is the Glenohumeral Joint, which generally refers to “The shoulder Joint”.
The most moveable joint.
The ulna runs parallel to the radius from the elbow to the wrist. Like the other arm bones, the ulna is relatively long and slightly curved. The primary function of the ulna is allowing motion and supporting the arm.
- The femur is the longest bone of the human skeleton, one of the strongest bones and supports weight and allows movement in the lower body.
Skull, ribs, breastbone, etc.
- Supports weight and allows many small movements.
Wrist bone,ankle bones and the vertebrae.
- Fixed Joints that are fused by a protein called Collagen, this allows little or no movement at all.
- The wide range of motion of the human body is due to the presence of freely movable joints.
Allow the bones limited movement. Slightly Movable Joints are found between bones of the rib cage.
Allows the movement in all directions.
Shoulder Joints and Hips.
Allows the sliding motion (back and forth movement)
Wrist and Ankles
Allows the rotation, bending, and straightening motion.
