Random
100
Dura Mater, Arachnoid and Pia Mater
What are the meninges?
100
Cell body, Axon (carries impulses away from cell body), Dendrite (carries impulses to the cell body), Myelin Sheath
What are the parts of the neuron?
100
Judgement, affect, personality, inhibitory center
What is the area 9-12 in the frontal lobe?
100
CNS protection, compensatory mechanism, nutrition
What is the function of CSF (cerebrospinal fluid)?
100
Network of neurons throughout the brain stem that is responsible for the sleep-wakefulness cycle, vital role in arousing and maintaining consciousness
What is the Reticular Activating System?
200
Thick non-elastic structure, lines the inside of the skull and the vertebral column, blood supply, Falx Cerebri, Tentorium Cerebelli
What is the Dura?
200
Oligodendrocytes, Schwann cells
What produces the Myelin sheath in the CNS and PNS?
200
Primary auditory, gustatory, olfactory
What is area 41-42 in the temporal lobe?
200
500 cc/day, 20-25 cc/hr, 130-150 CNS total
What is the production rate of CSF?
200
Nuclei of CN V, VI, VII, VIII, relays info to and from the cortex and the cerebellum and the body, Pneumotaxic center of Respiration
What is the Pons?
300
Transfer of CSF to venous system
What is the Arachnoid Villi?
300
Outermost layer of nerve fibers in the PNS, instrumental in regenerating the nerve fiber if it has been cut or crushed
What is the Neurolemma?
300
Primary sensory cortex-tactile sensation and proprioception
What is area 1-3 in the parietal lobe?
300
Fornix (role in memory), Hippocampus (new memory and learning), Amygdala (flight or fight mechanism, self preservation)
What are the three main parts of the limbic system?
300
Branches to form the opthalmic artery and the anterior circulation of the brain (anterior cerebral artery, middle cerebral artery)
What is the Internal Carotid Artery?
400
Thin, transparent membrane adherent to the surface of the brain, choroid plexus
What is Pia Matter?
400
most numerous cells of the CNS, provide support structure for the neuron
What are astrocytes?
400
Primary visual cortex
What is area 17 in the occipital lobe?
400
Located on either side of the third ventricle, last area where sensory impulses are processed before ascending to the cortex
What is the thamalus?
400
Anastomosis of arteries at the base of the brain that provides collateral circulation to ensure cerebral blood flow
What is the Circle of Willis?
500
Tent-like structure of dura that separates the occipital lobe from the cerebellum, or the supratentorial from the infratentorial space
What is the tentorium?
500
Breakdown of this barrier leads to vasogenic cerebral edema, secondary to osmotic pressure gradients
What is blood brain barrier?
500
Primary motor cortex-Here all voluntary movement is set into action contralateral in control, upside down according to body geography
What is area 4 in the frontal lobe?
500
connects hypothalamus w/ pituitary gland
What is the Infundibulum?
500
Largest branch of the ICA, supplies lateral surface of hemisphere, penetrates internally to the internal capsule and the basal ganglia
What is the Middle Cerebral Artery?
