the brain and spinal cord via cranial and spinal nerves
|! |! |! |! |! |! |! |! |!
integrative function (interneurons) - Correct answer ✔integrates sensory

information by analyzing and storing it |! |! |! |! |!
motor function (efferent neurons) - Correct answer ✔information from the
|! |! |! |! |! |! |! |! |! |!
brain and spinal cord is sent out to muscles or glands (effectors)
|! |! |! |! |! |! |! |! |! |! |!
brain - Correct answer ✔-control center of the human body
|! |! |! |! |! |! |! |! |!
-center of intelligence, behavior, memory and emotion
|! |! |! |! |! |!
-coordinates activity of skeletal muscles |! |! |! |!
-influences activity of visceral organs and glands |! |! |! |! |! |!
right cerebral hemisphere - Correct answer ✔music, face recognition, visual
|! |! |! |! |! |! |! |! |! |!
imagery, spatial abilities |! |!
left cerebral hemisphere - Correct answer ✔language, logic, reason
|! |! |! |! |! |! |! |!
,frontal lobe - Correct answer ✔reasoning, planning, part of speech and
|! |! |! |! |! |! |! |! |! |! |!
movement, emotions, problem solving |! |! |!
parietal lobe - Correct answer ✔perception of stimuli related to touch,
|! |! |! |! |! |! |! |! |! |! |!
pressure, temperature, pain |! |!
temporal lobe - Correct answer ✔perception and recognition of auditory
|! |! |! |! |! |! |! |! |! |!
stimuli and memory |! |!
occipital lobe - Correct answer ✔many aspects of vision
|! |! |! |! |! |! |! |!
insula lobe - Correct answer ✔integrates autonomic information, associated
|! |! |! |! |! |! |! |! |!
to visceral function
|! |!
meninges - Correct answer ✔-connective tissue coverings that surround the
|! |! |! |! |! |! |! |! |! |!
brain and spinal cord
|! |! |!
functions:
-protect underlying neural tissues
|! |! |!
-anchor the brain in cranial cavity and spinal cord in vertebral cavity
|! |! |! |! |! |! |! |! |! |! |!
dura mater - Correct answer ✔-most superficial layer
|! |! |! |! |! |! |!
--outer layer fuses with periosteum of skull
|! |! |! |! |! |!
--inner layer folds into parts of cranial cavity
|! |! |! |! |! |! |!
, major dural folds:
|! |!
-falx cerebri
|!
-falx cerebelli
|!
-tentorium cerebellli |!
cerebrospinal fluid (CSF) - Correct answer ✔functions:
|! |! |! |! |! |!
-cushioning and shock absorption |! |! |!
-chemical protection |!
-exchange nutrients and wastes |! |! |!
blood brain barrier - Correct answer ✔-protective mechanism that maintains
|! |! |! |! |! |! |! |! |! |!
stable environment for the brain
|! |! |! |!
-capillaries of the brain are the least permeable of any capillaries in the body
|! |! |! |! |! |! |! |! |! |! |! |! |!
-capillaries are selective partly due to presence of astrocytes
|! |! |! |! |! |! |! |!
cerebrum - Correct answer ✔functional areas:
|! |! |! |! |!
-sensory areas |!
-motor areas |!
-association areas |!
primary motor area - Correct answer ✔location: precentral gyrus in frontal
|! |! |! |! |! |! |! |! |! |! |!
