10.17 Introduction to the Nervous System Flashcards
- cingulate gyrus
- insula
the first part of the name in the tract tells you: the second part of the name in the tract tells you:
where the cell bodies are where the axons terminate
motor neurons that innervate smooth muscle, cardiac muscle, and glands stop at a _____________ along the way to their target.
autonomic ganglion
where is the primary somatosensory cortex? (lobe)
what is this gyrus called
the parietal lobe
the post-central gyrus
- central sulcus
- lateral sulcus
what are the functions of the limbic system?
emotion
learning and memory
motivation
behavior
olfaction
lemniscus is a collection of ______________.
axons
what do the basal ganglia do?
initiation of movement
thoughts
reward
etc
what is the limbic lobe made up of?
the cingulate gyrus
the parahippocampul gyrus
- third ventricle
- aqueduct
- cistern
what are the main functions of the brainstem
autonomic control (breathing, heart)
cranial nerves
long tracts
level of consciousness
what is the major functions of the temporal lobe?
Function is hearing (houses primary auditory cortex), higher order visual functions
houses some areas of the limbic system – learning and memory. Hippocampus and amygdala.
the brainstem consists of what structures?
midbrain
pons
medulla
the diencephalon consists of what structures?
the hypothalamus
the thalamus
the pineal gland
longitudinal fissure
central fissure
lateral fissure (sulcus)
what are the functions of the parietal lobe?
somatosensory cortex
spatial awareness
motor neurons that innervate skeletal muscle use how many neurons to get there? motor neurons that innervate smooth muscle, cardiac muscle, and glands use how many neurons to get there?
one two
the forebrain contains what two divisions?
the cerebran hemispheres
the diencephalon
fasciculus is a collection of ______________.
axons
what is is called when a distal process that is disconnected slowly degenerates and is phagocytosed?
wallerian degeneration
what gyrus always sits directly above the corpus collosum?
the cingulate gyrus
where is the primary motor cortex located? (lobe)
what is the gyrus called?
in the frontal lobe
the pre-central gyrus
what are the functions of the frontal lobe?
is movement (primary motor cortex) and personality, insight, foresight.
what makes up the limbic system?
the cingulate cortex
hippocampus
amygdala
insula
discrete collection of cell bodies in the CNS
nucleus
what is the main function of the cerebellum?
coordination
peduncle is a collection of ____________.
peduncle
discrete collection of cell bodies in the PNS
ganglion
