Cards

Term
medulla oblongata
Definition

contains: reticular formation, cardiovascular center, respiratoy rhythmicity center

 

functions: relays sensory information to thalamus and other portions of the brain stem

- regulates vital autonomic functions

Term
reticular formation
Definition

contains: loosely organized mass of grey matter and embedded nuclei from medulla oblongata to midbrain

 

functions: regulation of vital autonomic functions, arousal, maintains consciousness

 

Term
cardiovascular center
Definition

functions: adjusts heart rate, strength of cardiax contractions and PNS blood flow

Term
respiratory rhymicity center
Definition
function: set basic pace for respiratory movements
Term
pons
Definition

functions: relays sensory info to cerebellum & spinal cord

-relaxation

Term
midbrain
Definition

contains: corpora quadrigemmina, superior/inferior colliculi, cerebral peduncles

 

functions: allows the brain to communicate with the rest of the nervous system

 

 

Term
corpora quadrigemmina
Definition

contains: two pairs of sensory nuclei, grey matter, superior/inferior colliculi

 

functions: processes visual and auditory sensations

Term
superior colliculi
Definition
function: initiates reflex responses to visual stimuli
Term
inferior colliculi
Definition

functions: initiates reflex responses to auditory stimuli

Term
cerebral peduncles
Definition

contains: nerve fiber bundles on the surface near the midbrain

 

functions: connects primary motoe cortex with motor neurons in the brain and spinal cord, carries ascending sensory info to the thalamus

Term
cerebellum
Definition

function: coordinated complex somatic motor patterns

-adjusts output of other somatic motor centers in the brain and spinal cord

-motor snd sensory association

-coordinates fine tune movements and balance

Term
diencephalon
Definition
contains: thalamus, hypothalamus, epithalamus
Term
epithalamus
Definition

contains: pineal gland

 

functions: endocrine gland that secretes melatonin that controls basic awake/sleep patterns

Term
thalamus
Definition

contains: anterior nuclear group

 

functions:relays and processes centers for sensory info

Term
hypothalamus
Definition

regulates: thirst, appetite, emotions, sleep patterns, and the release of hormones from the pituitary gland

Term
corpus callosum
Definition

contains: fiber tract that links two cerebral hemispheres

 

functions: connectd right and left brain

Term
limbic lobe
Definition

contains: gyri, curves along the corpus callosum and continues on the surface of the cerebral

 

functions: emotional states, conscious intellectual and subconscious autonomic functions, motivation, fight/flight

Term
amygdala
Definition

contains: interface between the limbic system, cerebellum, and various sensory systems

 

functions: regulates heart rate, right/flight response, links emotions and memories

Term
hippocampus
Definition

functions: important to learning, long term memory storage and retrieval

Term
pituitary gland
Definition

contains: endocrine gland connected to the hippocampus

 

functions: regulates growth, puberty, metabolism, and stress

Term
frontal lobe
Definition

contains: prefrontal area, broca's area, premotor cortex, primary motor cortex, frontal eye field

 

functions: voluntary control of skeletal muscles, decision making, seed of your personality

Term
broca's area
Definition
function: speech, breathing, vocalization
Term
parietal lobes
Definition

contains: central sulcus, primary somatosensory cortex, somatosensory association area, wernicke's area, gustatory area, sensory cortex and motor cortex

 

functions: touch, pain, pressure, temperature, vibration, and taste

Term
wernicke's area
Definition
function: understanding language
Term
occipital lobe
Definition

contains: primary visual area, visual association area

 

functions: processing of visual information

Term
temporal lobe
Definition

contains: auditory association area

 

function: auditory and smell (olfactory) association, and memory retrieval
