Organization of the nervous system
This part of the nervous system consists of the Brain and the spinal cord.
Central Nervous System
Supporting cells in the CNS referred to as "nerve glue".
Neuroglia
Most superior part of the brain
cerebrum
What is a nerve?
a bundle of neuron processes wrapped in connective tissue coverings.
a disability where voluntary muscles are poorly controlled and spastic because of brain damage.
cerebral palsy
This part of the nervous system contains all parts of the nervous system outside of the central nervous system.
peripheral nervous system
This is the metabolic center of the neuron.
Cell body
deep groves in the cerebrum
Fissures
12 pairs of nerves that extend from the brain to serve the head and neck region
Cranial nerves
Results when vertebrae form incompletely
Spina Bifida
This part of the nervous system consists of nerves that convey impulses to the central nervous system.
Sensory division or afferent division
This substance covers nerves in a whitish, fatty material.
Myelin
the cerebral cortex is in charge of what actions that you do?
Speech, memory, logical and emotional responses, consciousness, and interpretation of sensation.
what are the spinal nerves?
31 pairs of nerves are formed by the union of the dorsal and ventral roots of the spinal cord on each side
A type of low blood pressure resulting from changes in body position.
Orthostatic hypotension
This part of the nervous system carries impulses from the CNS to effector organs, the muscles and glands.
motor or efferent division
what happens when a neuron has fewer positive ions sitting on the inner face of the neurons plasma membrane than there are on its outer face?
The neuron is polarized
a specialized cortical artery that is very involved in our ability to speak.
Broca's area
Composed of neurons that regulate the activity of smooth and cardiac muscles and glands.
Autonomic nervous system
What is the cause of arteriosclerosis?
Decreased elasticity of the arteries
This part of the nervous system regulates events that are involuntary, such as the activity of smooth muscle, cardiac muscle, and glands.
Autonomic Nervous system
Rapid, predictable, involuntary movements to stimuli.
Reflexes
the thing that connects the cerebral hemispheres.
Corpus Callosum
Where are preganglionic neurons located?
in gray matter of the cord
This disability is characterized by forgetfulness, irritability, difficulty in concentrating and thinking clearly, and confusion.
Senility
