Nervous Anatomy Lab Quiz Flashcards
What are the two main sections of the nervous system?
Central and Nervous systems
What are the autonomic subcategories of the nervous system?
Sympathetic
Parasympathetic
What are the meninges?
Protective layers protecting the brain and spinal cord
What are gyrus’?
Ridges in the cerebral cortex
What is the sulcus?
Depression or groove in the cerebral cortex
What does the longitudinal fissure do?
Divides cerebrum into left and right hemispheres
Occipital lobe
Visual cortex
Parietal lobe
Somatosensory cortex
Temporal lobe
Auditory cortex
Frontal lobe
Motor cortex
“Prefrontal cortex”
Pons
breathing, sensations
Medulla
body maintenance/survival
Cerebellum
movement, control, coordination
Superior and inferior colliculus
Sensory information
- vision
- hearing
- motor control
Cerebral cortex
memory, attention, preception, awareness
Pituitary gland
growth and development
- endocrine functions
Thalamus
relays information between sensory organs and cortex
Hypothalamus
Autonomic system
- Hormone secretion/regulation
Limbic system
Emotion & memories
Where are grey and white matter present?
In the brain, brainstem, and spinal cord
Grey matter
contains cell bodies, dendrites, and axon terminals
- unmyelinated
- synapses occur
White matter
made of axons connection different parts of grey matter together
- myelinated
Where does the spinal cord extend?
extends from the medulla oblongata to the lumbar vertebrae
What is the spinal column made of?
Spinal cord + vertebrae
What is the spinal cord protected by?
Bone & meninges
What does the spinal cord do?
Communication between CNS and PNS
ecto- / exo-
outer, outside, situated on
anti- / contra-
against / opposite
cephal / capit
head
crani
cranium / skull
encephala
brain
myel
spinal cord / bone marrow / myeline sheath of nerve fibers
-tomy
