Anatomy Brain & Cranial Nerves

Important nuclei in medulla oblongata

cardiac center, vasomotor, repiratory, olivary nuclei-motor & sensory

ascending cuneate nuclei & spinothalmic tracts

carry sensory signals

descending corticospinal tracts

carry signals to spianl cord

pons

facial sensation and expression, fourth ventricle

midbrain: superior and inferior colliculi

part of the midbrain, control auditory and visual attention

midbrain: cerebral peduncles

coordinates and inhibts muscles control

reticular foramen

web of gray matter that does somatic motor, cardiovascular, pain, consciousness, and habituation

cerebellum

muscle control and fine motor control

thalamus

gateway to cerebral cortex

epithalamus

pineal gland- endocrine gland

hypothalamus

involved in hormone production

frontal lobe

cognition, speech

parietal lobe

senses, taste

temporal lobe

hearing, smell, learning, memory, some vision

occipital lobe principal visual center

principal visual center

insula

consciousness, pain, sensation, emotion

stellate cells

local processing of sensory info

pyramidal cells

output neurons of cerebrum

primary cortex

mechanical

association cortex

memory, emotion, & abstract →prefrontal cortex

basal nuclei

caudate nucleus, putamen, and globus pallidus - motor control

limbic system

emotion, memory, learning → hippocampus and amygdala

olfactory nerve

smell

optic nerve

visual information

trigeminal nerve

opthalmic: face, maxillary: cheek, mandibular: mandible

facial nerve

temporal, zygomatic, buccal, mandibular, cervical
