Let's Brainstorm!
What is a large commissure allowing for communication between sides of the central hemisphere?
What is the corpus callosum?
Is stimulated by environmental changes
What are Dendrites?
Stretch receptors of muscles and tendons that project to the cerebellum
What are propioreceptors?
Formed by the merging of the anterior
and posterior roots
functions to modulate ongoing
automatic activities
What is the Autonomic Nervous System?
This functions in visual/auditory reflexes, arousal and motor coordination.
What is the midbrain?
What is an Axon?
Layers of the eyeballs
What is the Tunica?
Contains the cell bodies of motor neurons
What is the anterior gray horn?
Each segment innervates a skin area
What is a dermatome?
Contains an enlargement on the anterior/inferior aspect of the brain stem.
What is the pons?
Is highly branched like neurons and not capable of impulses.
What is Neuroglia.
Instantly accommodates focus at different distances
What is the Lens?
Axon tracts that cross between sides of the CNS
What are Commissures?
“rest and digest”
What is Parasympathetic?
Is the second largest single structure of the brain.
What is the Cerebellum?
Is the specialized system of capillary
endothelial cells that protects the brain
from harmful substances
What is the Blood Brain Barrier?
Functions to sense sound and equilibrium changes
What is the Ear?
Axon fibers passing directly to and from the spinal cord
What are Roots?
how neurons integrate the receiving inputs from thousands of presynaptic neurons before the generation of a nerve impulse
What is synaptic integration?
Means "tree of life"
What is the arbor vitae?
Located in the PNS, form myelin sheaths surrounding axons
What are Schwann Cells?
malleus, incus, stapes
What are the Ossicles?
The center for spinal reflexes
What is the spinal cord?
Name the two divisions of the Nervous System
What are CNS and PNS?
