sulci

surface of the cerebrum

Diencephalon consists of

Epithalamus, thalamus, hypothalamus

Epithalamus

contains the hormone secreting pineal gland, an endocrine structure

Thalamus responsible for

sensory information relay and processing centers

Hypothalamus responsible for

Centers controlling emotions, autonomic functions, and hormone production

Mesencephalon responsible for

processing visual and auditory information, and coordinate direct reflexive somatic motor responses to these stimuli, maintaince of consiousness

Pons responsible for

somatic and visceral motor functions

Cerebellum responsible for

automatically adjusting motor activities on teh basis of sensory information and memories of learned patterns of movement

Medulla Oblongata responsible for

relays sensory information to the thalamus and to other brain stem centers, regulation of autonomic function, such as heart rate, blood pressure, and digestive activities

Primary motor cortex function is

Conscious control of skeletal muscles

Parietal lobe function is

Conscious perception of touch, pressure, vibration, pain, temperature, and taste

Occipital lobe function is

Conscious perception of visual stimuli

Temporal lobe function is

Conscious perception of auditory and olfactory stimuli

All lobes have association areas that have the function of

Integration and processing of sensory data; processing and initiation of motor activities

Primary sensory cortex function is

recieve somatic sensory information from touch, pressure, pain, taste and temperature receptors

Visual cortex function is

recieves visual information

Auditory cortex function is

hearing

Gustatory cortex function is

recieves information from taste receptors of the tongue and pharynx

somatic sensory association area function is

to allow you to comprehend the size, form, and texture of an object

somatic motor association area function is

uses memories of learned movement patterns to coordinate motor actitivities

Association fibers do what

interconnect portions of the cerebral cortex within the same cerebral hemisphere

Commissural fibers do what

permit communication between teh two hemispheres

Projection fibers do what

link the cerbral cortex to the diencephalon, brain stem, cerebellum, and spinal cord

Internal capsule is

the entire collection of fibers that make up the central white matter of the brain

Superior colliculi do what

integrate visual information with other sensory inputs; initiate reflex responses to visual stimuli

Inferior colliculi do what

relay auditory information to medial geniculate nuclei; initiate reflex response to auditory stimuli

Gray matter is associated with what cranial nerves?

Nerve V, Nerve VI, Nerve VII, and Nerve VIII

White matter is associated with what cranial nerves?

Nerve III, and Nerve IV

the enteric nervous system
