Chapter 14 Skeletal, Muscular, and Nervous Systems

cartilage

nonvascular, firm connective tissue found mostly in joints

ossification

(Osteogenisis) the process of bone formation; formation of the bony skeleton in embryos and bone growth goes in until early adulthood as body continues to increase in size

ligament

A strong band of connective tissue that connets bones to one another.

tendon

A band of fibrous connective tissue that connects muscle to bone.

scoliosis

The abnormal lateral curvature of the spine that is often congenital in origin is....

osteoporosis

A condition in which the body's bones become weak and break easily.

smooth muscles

Found in hollow (visceral) organs.Non-striated and involuntary. Uninucleate, spindle-shaped.

skeletal muscles

Muscles that are usually attached to a bone and are responsible for movement and stability of the body.

flexor

is the muscle that closes a joint

extensor

is the muscle that opens the joint

cardiac muscle

1. Forms the wall of the heart. 2. Is striated. 3. Is involuntary because it is not consciously controlled.

tendinitis

inflammation of the tendon

hernia

A protrusion of tissue under the skin through a weakened area of the body wall.

neurons

A nerve cell; the basic building block of the nervous system.

cerebrum

Largest part of brain, associated with higher order functioning including control of voluntary behaviour, e.g. Thinking, planning, perceiving, understanding language.

cell body

Processes nutrients and provides energy for the neuron to function; contains the cell's nucleus; also called the soma.

dendrites

A neuron's bushy, branching extensions that receive messages and conduct impulses toward the cell body.

axons

a part of a neuron that carries impulses away from the cell body

central nervous system

A subdivision of the human nervous system comprising the brain and spinal cord. Transmits & receives messages to & from the PNS

peripheral nervous system

A division of the nervous system consisting of all nerves that are not part of the brain or spinal cord.

spinal meninges

a series of specialized membranes that provide physical stability and shock absorption for neural tissues of the spinal cord

cerebrospinal fluid

Fluid in the space between the meninges that acts as a shock absorber that protects the central nervous system.

cerebellum

A large structure of the hindbrain that controls fine motor skills.

frontal lobe

Largest and longest lobe in each hemisphere. Located in the upper forward half. Association areas are involved with planning, problem-solving, personality, decision making, controlling emotions and speech production

parietal lobe

A region of the cerebral cortex whose functions include processing information about touch.

occipital lobe

An area at the back of each cerebral hemisphere that is the primary receiving area for visual information.

temporal lobe

An area on each hemisphere of the cerebral cortex near the temples that is the primary receiving area for auditory information

brain stem

Connection to spinal cord. Filters information flow between peripheral nervous system and the rest of the brain.

medulla oblongata

Part of the brainstem that controls vital life-sustaining functions such as heartbeat, breathing, blood pressure, and digestion.

The pons

lies directly above the medulla and anterior to the cerebellum (2.5 cm). It acts as a bridge connecting the spinal cord with the brain and parts of the brain with each other.

The midbrain

Mesencephalon

The thalamus

Secondary sensory neurons usually decussate to project to what structure?

The hypothalamus

Coordinates nervous and endocrine system through pituitary gland

The Autonomic Nervous System

The autonomic nervous system incorporates all the impulses that are done involuntarily, and are usually associated with essential functions such as breathing, heartbeat etc. However this type of system can further be broken down into the sympathetic and p

The sympathetic nervous system

�The sympathetic nervous system activates the fight or flight response.

The parasympathetic nervous system

it produces opposite effects of the sympathetic nervous system. It conserves energy and clams you by decreasing your heartbeat, lowering your blood sugar and so forth.

somatic nervous system

Division of the PNS that controls the body's skeletal muscles.

Epilepsy

A disorder of the central nervous system characterized by loss of consciousness and convulsions.

Cerebral palsy

A loss or deficiency of motor control with involuntary spasms caused by permanent brain damage present at birth
