| Question |
Answer |
| occipital lobe |
vision; integrating primary vision with other senses |
| insular lobe |
visceral functions, integrates autonomic info, motormemory |
| limbic system |
motivation, sex drive, emotional behaviour, memory, affect |
| hypothalamus |
homeostasis |
| hippocampal formation |
memory (Alzheimer's) |
| amygdala |
emotions and drives |
| basal ganglia |
motor learning, control of motor skills |
| commissural fibres |
between hemispheres ex: corpus callosum |
| association fibres |
within a hemisphere ex: arcuate fasiculus |
| projection fibres |
between cerebrum and neuroaxis ex: uncuate fasiculus |
| internal capsule |
very important projection fibres |
| thalamus |
major sensory relay center, adds emotion to sensations; arousal, attention, sleep/wake cycles;all senses except smell stop here on the way to conscious awareness |
| mamillary bodies |
important for memory, easily damaged by alcohol |
| pineal body |
gonad development, produces melatonin |
| hypothalamus |
control center for autonomic NS, links NS to endocrine system |
| subthalamus |
relay station in sensory motor control of voluntary movements |
| reticular formation |
alertness, focus attention, monitors input to thalamus |
| superior colliculi |
vision; visual reflexes |
| inferior colliculi |
auditory; auditory reflexes |
| substantia nigra |
produces dopamine; damage here = Parkinson's |
| oculomotor nerve |
(m) lift the eyelid/control position of eyeball; pupil constriction |
| basilar pons |
relay between cortex and cerebellum; forms peduncles |
| posterior pons |
CN nuclei for trochlear(m), trigeminal(s/m), abducens(m) |
| trochlear nerve |
(m)moves eyeball down and out |
| trigeminal nerve |
(s)face, scalp, teeth, front 2/3 of tongue, soft palate (m)mandibular area |
| abducens nerve |
(m)moves eyeball inward |
| facial nerve |
(m)to striated muscles of facial expression(s)glands, taste buds, external ear & tympanic membrane |
| vestibulocochlear nerve |
(s)hearing and balance |
| cerebellum |
monitors skilled motor behaviour; corrects mismatches in muscle coordination |
| archicerebellum |
sense body position; balance |
| paleocerebellum |
posture; gross movement of limbs |
| neocerebellum |
precision of force, direction and extent of voluntary movements |
| peduncles |
carry fibres from one place to another |
| olives |
(gray matter) info about where body parts are in relation to themselves |
| pyramidal decussation |
80 - 85% of fibres cross over here |
| glossopharyngeal nerve |
(s)back 1/3 of tongue, tonsils, middle ear |
| vagus nerve |
(m)laryngeal muscles, smooth muscles(s)throat & ear, soft palate |
| accessory nerve |
(m)trapezius and sternocleidomastoid |
| hypglossal nerve |
(m)muscles of the tongue |
| phrenic nerve |
innervates the diaphragm (m) and (s) |
| brachial plexus |
C5 - T1 muscles and skin of chest and upper limbs |
| lumbarsacral plexus |
trunk and lower limbs |
| receptors |
detect and respond to changes in internal and external environment |
| exteroreceptors |
mediate sight/sound/smell/balance/touch |
| proprioreceptors |
deep body sensation; our body parts in relation to space and each other |
| 2-point discrimination |
"tell me when you feel two pricks" |
| stereognosis |
ability to recognize object through touch alone |
| reflex |
behaviour that is not cortically mediated |
| cortical override |
consciously controlling reflexes |
| corticobulbar tracts |
from the cortex to the brain stem & vice-versa |
| cervical plexus |
