The Nervous System
What are the main components of the nervous system?
The brain, the spinal cord, and the neurons
Receives input from other neurons
Dendrites
Sensory area for vision
Occipital Lobe
How many pairs of cranial nerves are there?
12
What is the correct order of the meninges from superficial to deep?
What are the building blocks of the nervous system?
Neurons
Space between two neurons, the communication gap
Synapse
Area of the brain for remembering music and visual scenes
Sensory information for the sense of smell
Olfactory
What structure connects the left and right sides of the brain?
Corpus collosum
This layer resembles a spider's web
Arachnodnoid Mater
Lipid-rich layer that provides insulation and increases the smoothness of communication between neurons
Myelin Sheath
The cerebellum aids in the maintenance of these two things?
Balance and posture
Controls the movement of the tounge
Hypoglossal
The tree-like structure in the cerebellum
Arbor vitae
Masses of myelinated fibers appear this color
White
These make the myelin sheaths around the axons of neurons
Oligodendrites
If a person is having trouble forming the sounds for words, then they most likely have damage to this area of the brain.
Broca's
Responsible for equilibrium and hearing
Vestibulocochlear
The deep groove that separates the two hemispheres of the cerebrum is called this
Longitudinal fissure
Drugs such as meth and cocaine affect this part of the nervous system
Neurotransmitters/receptors
These cells connect blood vessels to neurons
Astrocytes
Relay station between the medulla oblongata and the cerebellum
Pons
Nerve responsible for swallowing, gag reflex, and speech. Also controls the muscles of the internal organs.
Vagus
These bumps and grooves increase the surface area of the brain
Gyrus and Sulcus
