basal ganglia function

Direct input from frontal lobe, facilitates motor movements, inhibits unneeded movements

Spatial-temporal aspects of speech

Damage: unusual body postures, dysarthria, change in body tone, involuntary uncontrolled movements interfere with voluntary speech, walk or other movements (dyskinesias)

amygdala function

Responsible for the response and memory of emotions, especially fear

thalamus function

relay station for sensory impulses, pain

hypothalamus function

water balance/bp/temp regulation/hunger/thirst/sex.

subthalamus function

Interacts with the basal ganglia to control movements.

superior colliculi function

visual reflexes

inferior colliculi function

auditory reflexes

insula function

Contains the Gustatory Cortex which is responsible for taste; interpretation of music

Wernicke's area function

controls language reception - a brain area involved in language comprehension and expression; usually in the left temporal lobe

vermis function

integration of information between the two cerebellar lobes; gross motor coordination timing, posture, locomotion

Broca's area function

Speech production area found in dominant hemisphere-> left; verbal expression of language

post-central gyrus function

sensory strip

receives pain, temperature and touch information from the body

pre-central gyrus function

primary motor cortex

mamillary bodies function

limbic system such as emotions

anterior cerebellar lobe function

- Receives information from the spinocerebellar tracts.

- Sends inhibitory fibers with the lateral vestibular tract.

Primarily associated with GAIT ATAXIA

Partially works with vermis

frontal lobe function

involved in motor function: problem solving, memory, judgment, impulse control

temporal lobe function

auditory

parietal lobe function

somatic sensory processing

occipital lobe function

visual processing

pineal body function

Secrete melatonin and is involved in regulation of sleep and sex behavior

substantia nigra function

secretes dopamine

Infundibulum function

Small funnel-like stalk that connects the pituitary to the brain and is the passage which pituitary hormones are delivered to the deeper parts of the brain

medulla oblongata function

regulating vital function (breathing, digestion, heart rate)

caudate nucleus function

learning and memory from feedback

filum terminale function

anchors spinal cord to coccyx

corpus callosum function

Connects the right and left hemispheres of the brain

olfactory nerve function

sensory, smell

optic nerve function

sensory, vision

occulomotor nerve function

Motor, Eye movement and pupillary constriction

vestibulocochlear nerve function

hearing, equillibrium (balance)

trochlear nerve function

motor, eye movement

facial nerve function

facial expression, taste

trigeminal nerve function

1. Ohpthalmic--Sensory--orbital

2. Maxillary--Sensory--upper teeth

3. Mandibular--Mixed--

Sensory--muscles for swallowing and anterior 2/3 of tongue

Motor--opening jaw, chewing (mastication)

hypoglossal nerve function

Movement of the tongue and for speech

glossopharyngeal nerve function

Sensory-Taste, respiration, blood pressure

Motor- Swallowing & gagging

abducens nerve function

lateral eye movement

vagus nerve function

Visceral muscle movement (heart, lungs, intestines)

accessory nerve function

swallowing, head, neck, and shoulder movements
