Skeletal System
made up of living tissues formed into different layers. The outer layer is hard, densely packed.
Bones
Any type of break in the bone
Fracture
Muscle that closes a joint.
Flexor
Areas of discolored skin that appear after an injury, or blow to the body.
Bruises
Or nerve cells transmit messages to an from the spinal cord and brain.
Neurons
The process by which bone is formed, renewed, and repaired.
Ossification
Results when a bone slips out of place, tearing the ligaments that attach to the bone at the joint.
Dislocation
Muscle that opens a joint
Extensor
Result when muscles are stretched or partially torn from over exertion.
Strains or Sprains
Transmit impulses away from the cell body and toward another neuron, muscle cell, or gland.
Axons
Band of fibrous, slightly elastic connective tissue that attaches one bone to another.
Ligament
Occurs when ligaments and tendons in the wrist swell.
Carpel Tunnel Syndrome
Muscles attached to bones that cause body movements.
Skeletal Muscles
Inflammation of a tendon can be the consequence of injury, overuse, or natural aging.
Tendonitis
Branched structures that extend from the cell body in most neurons. These receive information and transmit impulses toward the cell body.
Dendrites
A fibrous cord that attaches the muscle to the bone.
Tendon
Painful swellings of the bursae in the first joints of the big toes.
Bunions
A type of striated muscle that forms the wall of the heart.
Cardiac Muscle
Occurs when an organ or tissue protrudes through an area of weak muscle.
Hernia
This consists of the brain and Spinal Cord
Central Nervous System (CNS)
A strong, flexible connective tissue that can also act as a cushion between two bones to reduce friction.
Cartilage
Inflammation of a joint, resulting from an injury, natural wear and tar, or autoimmune disease.
Arthritis
Muscles that act on the lining of the body's passageways and hollow internal organs.
Smooth Muscles
An inherited disorder in which skeletal muscle fibers are progressively destroyed.
Muscular Dystrophy
Gathers information from inside and outside your body. This includes nerves that extend from the brain, spinal cord, and sensory receptors, such as those in the skin.
Peripheral Nervous System (PNS)
