Skeletal/Muscular System

thinner and much flatter than other bones; examples include the scapula, and those in the skull that protect organs

when swollen ligaments & tendons in the wrist cause numbness, burning, tingling, pain, and weakness in the hand

results from when a muscle is stretched or partially torn as a result of overexertion

have an oval shaped part that fits into a curved space, like your wrist

returning to homeostasis

nonprogressive neuro disorder - result a damage to brain - before, during, after birth or early childhood

controls the left side of the body, center for processing music and art

What is the largest part of the brain?

injury to the upper part of the spinal cord; paralysis of both upper and lower limbs

What are the three parts of the brain?

Disorder of nervous system electrical activity in the brain-recurrent seizures-sudden episodes of electrical activity

The Total Number of bones in the human body

paralysis of both lower limbs

Peripheral nervous system - heart rate up, blood vessels dilate, increased blood flow

can result from a sharp blow or the twisting of a joint

consists of 80 bones of the skull, spine, ribs, vertebrae, and Strenum

the broken end of the bone protrudes through the skin

formed when the rounded head of one bone fits into the rounded cavity of an adjoining bone; hip, or shoulder joint

an area of discolored skin that appears after an injury causes the blood vessels beneath the skin to rupture

found at the elbow, knee, ankle, and fingers - promotes a joint to bend and straighten

a condition in which progressive loss of bone tissue occurs

How much does the adult brain weigh? How long can it last without oxygen before permanent damage?

are almost equal in length and width examples include bones of the hands, wrists, feet, and ankles

contains the nucleus, the control center of the cell; regulates production of proteins within the cell

bone shatters into more than 2 pieces; severe force

the outer, hard layer, beneath that is spongy bone that is filled with red bone marrow

neuron's are destroyed; result in confusion, loss of memory, and gradual mental retardation

the process by which bone is formed, renewed, and repaired

receive information from other neurons and transmit impulses toward cell body

any break in a bone

an injury to a ligament in a joint

damage to tissues caused by prolonged, repeated movements

Peripheral nervous system

a lateral, or side to side, curvature of the spine

fracture is incomplete, and 2 parts of the bones do not separate

the broken bone does not protrude

Bones in legs and arms; humerus, femur, tibia, ulna

occurs when an organ/tissue protudes through weak muscle; can happen during weightlifting; surgery is required

painful swelling of the bursa in the first joint of the big toe

disease results in destruction of nerve cells in an area of brain helps coordinate skeletal muscle movement

a type of striated muscle that forms the wall of the heart

results from the inflammation of a fluid-filled sac called bursa; common at elbow

an inherited disorder in which skeletal muscle fibers are progressively destroyed; no cure

bruising of the brain that can result in swelling

a direct blow to the head

The central nervous system

composed of remaining 126 bones of the upper and lower limbs, shoulders, and hips

destruction of the myelin sheath that surrounds the axons of neurons in the CNS

a fibrous cord that attaches muscles to the bone or other muscle

irregularly shaped bones, such as some facial bones or the vertebrae that have unusual shapes

results when ligaments that attach the bone at the joint are torn as the bone slips out of place

are attached to bone and cause body movements

transmit impulses away from the cell body and toward another neuron

a band of fibrous, slightly elastic connective tissue that attaches bone to bone

A strong, flexible connective tissue

may result in a temporary loss of consciousness

allow limited rotation or turning of the head

controls right side of body; center for language, reasoning, and to analyze and think critically

long column of nerve tissue; about 18 inches down your back

inflammation of a tendon, caused by injury, overuse, or natural aging

Causes of cerebral palsy include:

fracture is completely across the bone; from a direct blow, or from stress caused by prolonged running on a damaged bone

the lobe of the brain that controls vision

the lobe of the brain dealing with censory information, heat, cold, pain touch, body position

act on the lining of passageways and internal organs

inflammation of a joint; can result from wear and tear on the joints
