The Skeletal System is the framework of the body‚ consisting of 206 bones as well as a network of tendons that is made of tough band of fibrous collagen tissue connecting a muscle to bone‚ ligaments connecting bones to joint and cartilage that allows some flexibility of movement. The skeletal system serves 4 functions: (1) Giving the body its shape (2) Protecting the vital internal organs (3) Allowing for movement (4) Storing minerals and producing blood cells The skeletal system has 6 basic components:

In endochondral ossification bone tissue replaces hyaline cartilage‚ forming all bones below the skull except for the clavicles. (1) Osteoblasts secrete osteoid‚ creating a bone collar around the diaphysis of the hyaline cartilage model. (2) Cartilage in the center of the diaphysis calcifies and deteriorates‚ forming cavities. (3) The periosteal bud invades the internal cavities and spongy bone forms around the remaining fragments of hyaline cartilage. (4) The diaphysis elongates as

BI309 Lab-2 Name of student: Anisa Dreunibakarua ID #: S11033198 Title: Effect of Temperature and Stimuli on Simple Muscle Twitch. Introduction: Skeletal muscle is a type of striated muscle that is attached to skeleton to facilitate movement by applying force to bones and joints through contraction. Skeletal muscle generally contract voluntarily when stimulated by the nerve‚ although they can also contract involuntarily at times. Muscle action is controlled by the Nervous System

Function of the Skeletal System 1. Support 2. Movement: The bones of the upper and lower limbs pull and push‚ with the help of muscles. 3 storage as a mineral store. 97% of the body’s calcium is stored in bone. Here it is easily available and turns over fast. In pregnancy the demands of the fetus for calcium require a suitable diet and after menopause hormonal control of calcium levels may be impaired: calcium leaches out leaving brittle osteoporotic bones. 4. Protective. Skull for the brain
