100
A specialized muscle cell that responds to stretch and is involved in the stretch reflex
What is a muscle spindle
100
Brain structure that controls balance and posture
What is the cerebellum
100
Is associated with skeletal muscle and voluntary movement
What is the somatic nervous system
100
Mandibular, maxillary, opthalmic
What are the three divisions of the trigeminal nerve?
100
The most common sensory receptor
What are free nerve endings
200
Prevents contracting muscles from applying excessive tension to tendons
What is the golgi tendon reflex
200
Is the major tract for communication between hemispheres
What is the corpus callosum
200
Controls smooth and cardiac muscle and glands
What is the autonomic nervous system
200
Innervates biting, chewing, and swallowing
What is the trigemminal nerve
200
Associated with light touch and superficial pressure
What are Merkel Disks
300
Spinal nerves indicated by capital letter and number; skin area supplied with sensory innervation by spinal nerves
What is the dermatomal map
300
Is found in the cerebrum, diencephalon and midbrain and controls motor function
What is the basal nuclei
300
Consists of nerves plexuses within the wall of the digestive tract and is turned up or down by the ANS
What is the enteric nervous system
300
The largest cranial nerve
What is the trigeminal nerve
300
Senses deep cutaneous pressure and vibration
What is pacinian corpuscles
400
Involves both excitatory and inhibitory interneurons to “antagonizing” muscles
What is reciprocal innervation
400
Is associated with with medulla and is continuous with the spinal cord and completes the flow around the brain
What is the fourth ventricle
400
Activates the adrenal gland which releases epinephrine into blood
What is the sympathetic NS
400
Is involved in eye blinking, tear glands, facial expressions, and some taste
What is the facial nerve
400
Involved in pain, itch and temperature and the sensory information crosses over right away
What is the anterior spinothalamic tract
500
Involves two excitatory interneurons but on opposite sides
What is the crossed extensor reflex
500
Glial cells that create the blood brain barrier
What is astrocytes
500
Reaches organs through cranial nerves as opposed to spinal nerves
What is the parasympathetic NS
500
Controls the heart and GI through parasympathetic stimulation
What is the vagus nerve
500
Involved in less precise movements, modifications, and balance
What are the indirect motor nerve pathways (extrapyramidal)?
