Anatomy Flashcards
1
Q
Spinal Cord
A
- receives/processes sensory info (from skin/joints/muscles)
- controls movements (limb/trunk)
2
Q
Grey Matter
A
nerve cell bodies
3
Q
White Matter
A
ascending and descending tracts of myelinated axons
4
Q
Brain Stem
A
- receives sensory info (skin/muscles-head/neck/face)
- provides motor control (muscles)
- site of entry for info from hearing/balance/taste
- mediates parasympathetic reflexes
- conveys info from spinal cord brain)
- regulates levels of arousal/awareness
5
Q
Cerebellum
A
- important for maintain posture and coordination of movement (btwn head/eyes/limbs)
- critical in learning motor skills
- connects w/ cerebral cortex
- involved w/ language
6
Q
Diencephalon
A
- thalamus (processes most info reaching cerebral cortex)
- hypothalamus (regulates homeostasis/autonomic/endocrine/visceral functions
7
Q
Frontal Lobe
A
- short-term memory
- planning future actions (control of movement)
8
Q
Parietal Lobe
A
- somatic sensation
- forming body image
- relating to extrapersonal space
9
Q
Occipital Lobe
A
vision
10
Q
Temporal Lobe
A
- hearing
- deeper regions (hippocampus & amygdaloid) w/ learning/memory/emotion
11
Q
Afferent Neuron
A
- sensory/receptor
- Dorsal
12
Q
Efferent Neuron
A
- motor/effector
- Ventral
13
Q
Peripheral Nervous System (PNS)
A
- Sensory
- Motor
14
Q
Sensory (PNS)
A
- Somatic (touch/pain/pressure/vibration)
- Visceral (stretch/pain/temp/chem changes)
15
Q
Motor (PNS)
A
- Somatic (motor innervation - all skeletal muscles
- Autonomic (motor innervation - smooth muscle/cardiac muscle/glands)
