Nervous system structural divisions CNS (brain and spinal cord)
PNS
SNS
ANS (Sympathetic and parasympathetic)
Meninges lie between the skull and brain and has three layers
Dura matter outer layer of meninges
Arachnoid middle meningeal layer, two layer membrane that
covers the folds and fissures of the brian
Pia matter inner meningeal layer that contains small blood
vessels that supply blood to the brain
Cerebral spinal fluid colorless, odorless, fluid containing: glucose,
electrolytes, oxygen, water, carbon dioxide, protein,
leukocytes
CSF provides cushion, maintains normal intracranial pressure,
provides nutrition, and removes metabolic waste.
Where is CSF produced? within 4 ventricles found within the brain
Where are the ventricles located? 1 lateral ventricle in each hemisphere, third ventricle
adjacent to thalamus, fourth adjacent to the
brainstem
,Grey matter consists of cell bodies
White matter myelinated nerve fibers
Arteries Carotid arteries supply most of the blood to the
brain and branch off into the posterior, middle, and
anterior cerebral arteries. Vertebral arteries branch
into the posterior and anterior communicating
arteries
Circle of Willis A circle of arteries at the base of the brain that
supply blood to the brain
Cerebrum largest part of the brain and is composed of two
hemispheres which contain frontal, parietal,
temporal, and occipital lobes.
Frontal Lobe contains primary motor cortex and is responsible for
functions related to voluntary motor activity and
controls intellectual function, awareness of self,
personality, and autonomic responses related to
emotion
Broca's area Left frontal lobe; formulation of words (expressive
aphasia)
Parietal lobe contains the sensory cortex which its major function
is to receive sensory input such as position sense,
touch, shape, and texture of objects
Temporal Lobe contains primary auditory cortex
Wenicke's area Left temporal lobe only, next to primary auditory
cortex connected to Broca's area by a bundle of
nerves (arcuate fasciculus). Responsible for
comprehension of speech, also involved in speech
production, interpreting the sounds
, What happens when both Broca and Patient has global aphasia
Wernike's areas are damaged?
Occipital Lobe contains the primary visual cortex and is responsible
for reviewing visual information.
Diencephalon made up of the thalamus, hypothalamus,
epithalamus, and subthalamus.
Hypotha Regulation of body temperature, Hunger, Thirst,
Formation of autonomic nervous system responses,
Storage and secretion of hormones from the pituitary
gland
Basal ganglia Creates smooth, coordinated voluntary movement by
balancing the production of two neurotransmitters:
acetylcholine and dopamine
Brain stem 10 of the 12 cranial nerves originate from the
brainstem. The occulomotor nerve (CN III) and
trocholear nerve (CN IV) originate in the midbrain
Medulla oblongata Contains reflex centers for controlling involuntary
functions such as breathing, sneezing, swallowing,
coughing, vomiting, and vasoconstriction
Spinal nerves 31 pairs emerge from different segments of the spinal
cord
8 pairs of cervical
12 pairs of thoracic
5 pairs of lumbar
5 pairs of sacral
1 pair of coccygeal nerves
The first 7 pair of nerves exit above their
corresponding vertebrae. The remaining spinal
nerves exit below the corresponding vertebrae
