NEURO Flashcards
central nervous system is consist of
brain and spinal cord
4 major divisions of brain
CEREBRUM
DIENCEPHALON
BRAIN STEM
CEREBELLUM
4 lobes of cerebrum
frontal
temporal
parietal
occipital
a bundle of nerve fibers responsible for communication between the hemispheres.
corpus callosum
lies beneath the cerebral hemispheres and consists of the thalamus and hypothalamus.
Diencephalon
is responsible for regulating many body functions including water balance, appetite, vital signs (tem- perature, blood pressure, pulse, and respiratory rate), sleep cycles, pain perception, and emotional status
Hypothalamus
3 parts of brain stem
mid- brain, pons, and medulla oblongata
serves as a relay center for ear and eye reflexes, and relays impulses between the higher cerebral centers and the lower pons, medulla, cerebel- lum, and spinal cord.
Midbrain
Links the cerebellum to the cere- brum and the midbrain to the medulla. It is responsible for vari- ous reflex actions.
Pons
contains the nuclei for cranial nerves, and has centers that control and regulate respira- tory function, heart rate and force, and blood pressure.
Medulla oblongata
primary functions include coordination and smoothing of voluntary movements, main- tenance of equilibrium, and maintenance of muscle tone.
Cerebellum
Directs voluntary, skeletal actions (left side of lobe controls right side of body and right side of lobe controls left side of body). Also influences communication (talking and writ- ing), emotions, intellect, reasoning ability, judgment, and behavior. Contains Broca’s area, which is responsible for speech.
Frontal lobe
Interprets tactile sensations, including touch, pain, temperature, shapes, and two-point discrimination.
Parietal
Influences the ability to read with understand- ing and is the primary visual receptor center.
Occipital
Receives and interprets impulses from the ear. Contains Wernicke’s area, which is respon- sible for interpreting auditory stimuli.
Temporal lobe
