Chapter 7.6 Nervous System

What is the autonomic nervous system?

• The division of the nervous system consisting of the brain and spinal cord

• Division of the nervous system concerned with reflex, or involuntary, activities of the body

• the division of the autonomic nervous system that calms the body, conserving its energy

What is the thalamus?

• Structure in the diencephalon of the brain that acts as a relay center to direct sensory impulses to the cerebrum

• Portion of the brain stem responsible for conducting messages to other parts of the brain and for certain reflex actions

• Membranes that cover the brain and spinal cord

What is Parkinson's Disease?

• Nerve pain caused by inflammation, pressure, toxins, and other diseases

• paralysis of the arms, legs, and body below the spinal cord injury

• Chronic progressive degeneration of brain cells, usually in people over 50 years of age

What is the central nervous system?

• Part of the nervous system apart from the brain and spinal cord

• The division of the nervous system consisting of the brain and spinal cord

• the division of the peripheral nervous system that controls the body's movement and sensation

What is the basic structural unit of the nervous system?

• Neuron

• Nucleus

• dendrites

• Axon

What is the function of the meninges?

• Shock absorbers to protect, carries nutrients and removes wastes

• Balance state in the body

• Spaces between axon of a neuron and dendrites of other neurons

• A membrane that cover and protect brain and spinal cord

Abnormal electrical impulses in the neurons of the brain

• Shingles

• Multiple sclerosis

• Epilepsy

• Hydrocephalus

This part of the brain is responsible for muscle coordination, balance and posture and muscle tone

• Ventricles

• Midbrain

• Cerebellum

• Pons

A condition that can be caused by an obstruction of blood flow to the brain or a hemorrhage

• Multiple sclerosis

• Cerebrovascular accident (CVA)

• Shingles

• Hydrocephalus

A single nerve fiber that carries impulses away from the cell body

• Nucleus

• dendrites

• Axon

• Myelin sheath
