Neuroanatomy Flashcards
1
Q
Central NS
A
- brain, brainstem, spinal cord
- gray matter = unmyelinated, capillaries, glial cells, dendrites
- white mater = myelinated, nerve fibers
2
Q
Peripheral NS
A
- cranial and spinal nerves
- unprotected
- anterior root: motor away from CNS
- posterior root: sensory towards CNS
3
Q
Autonomic NS
A
- sympathetic and parasympathetic system
- homeostasis and response to stress
4
Q
Somatic NS
A
- peripheral and motor nerve fibers
- all are myelinated
- controls voluntary movements
5
Q
Limbic System
A
- involved in mood/emotion/memory/smell/appetite
6
Q
Telencephalon
A
cerebrum, amygdala, hippocampus, basal ganglia
7
Q
Cerebrum
A
- L and R hemispheres
- outer is grey, inner is white matter
8
Q
Frontal
A
- motor cortex
- broca’s area (speech, concentration)
- personality, temper, judgement, reasoning
9
Q
Temporal
A
- auditory processing and olfaction
- Wernicke’s area (ability to understand and produce meaningful speech)
- interpretation of emotions and reactions
10
Q
Parietal
A
- touch, kinesthesia, vibration, temperature
- receives info regarding hearing, vision, motor, sensory, and memory
- meaning for objects, interprets language and words
- spatial and visual perception
11
Q
Occipital
A
- visual information
- judging distance and seeing in 3D
12
Q
Hippocampus
A
- stores and forms new memories
- language
13
Q
Basal Ganglia
A
- voluntary movement
- autonomic movement (tone, posture, motor responses)
- associated with PD, huntington’s, tourettes, ADD, OCD
14
Q
Amygdala
A
- emotional and social processing
- fear, pleasure, arousal, memory
15
Q
Diencephalon
A
- where motor and sensory tract synapse
- thalamus, hypothalamus, subthalamus, epithalamus
