VERIFIED SOLUTIONS 2024
Meninges - ANSWER membranes that encase the CNS
Dura mater - ANSWER ◦is the outer and toughest layer
Arachnoid layer - ANSWER is the middle layer with a spider web-like vascular system
Pia mater - ANSWER ◦is the innermost layer that rests directly on the brain and spinal cord
Cerebrospinal fluid - ANSWER plasma like liquid that fills the space between the arachnoid and the pia
mater layers to provide additional cushion and support to the CNS
Neural tissue consists of two types of cells - neuroglia and neurons - ANSWER ◦Neuroglia cells provide
support
Trigeminal neuralgia - ANSWER ◦excruciating pain that radiates along the side of their face induced by
shaving and while eating
Neurons - ANSWER ◦Fundamental units of the nervous system
◦Generate and transmit bioelectrical impulses
◦Do not have the ability to divide
◦Losses due to aging or injury cannot be replaced
◦Not all cell death results in loss of functioning
Axon - ANSWER ◦extends away from the cell body, carrying impulses to another neuron, muscle cell, or
organ cell
, Dendrites - ANSWER ◦projections that transmit impulses toward the cell body
Myelin sheath - ANSWER ◦surrounds some axons and increases the rate of impulse transmission
White matter - ANSWER ◦bundles of myelinated nerves
Human Brain - ANSWER ◦One of the largest and most complex organs in the human body
◦Contains more than 100 billion nerves that communicate to trillions of synapses
◦Responsible for a variety of physiologically vital functions and cognitive activities
The cerebrum - ANSWER ◦the largest of the regions (accounting for 80% of the brain's total mass),
controls the higher thought processes
The cerebrum is divided into right and left hemispheres, impinging one hemisphere on the other can
have significant—even life-threatening—effects.
cerebral cortex - ANSWER A thin layer of gray matter, ◦surrounds the cerebrum
◦A thick central core of white matter lies beneath the gray matter. This white matter contains bundles of
axons that transmit impulses from the cerebral
Frontal lobe - ANSWER ◦facilitates voluntary motor activity and plays a role in personality traits
Parietal lobe - ANSWER ◦receives and interprets sensory input except for smell, hearing, and vision
stimuli
Occipital lobe - ANSWER ◦processes visual information
Temporal lobe - ANSWER ◦is essential for hearing and memory
