Study Guide For Exam Two

Choroid plexus in the lateral ventricles produces CSF. CSF flows through interventricular foramina into third ventricle.Choroid plexus in the third ventricle adds more CSF.CSF flows down cerebral aqueduct to fourth ventricle.Choroid plexus in the fourth ventricle adds more CSF.CSF flows out two lateral apertures and one medial aperture.CSF fills subarachnoid space and bathes external surfaces of brain and spinal cordAt arachnoid villi, CSF if reabsorbed into venous blood of dural venous sinuses.

• Heat sensation would be detected by the sensory receptors of the somatic sensory in the Afferent Division of the peripheral
• nervous system. This information is then sent to the central nervous system who would make the decision to remove the hand then send the information back to the peripheral nervous system though the efferent division to somatic sensory's skeletal muscle effector who would the move the hand

Nausated feeling would be detected by the sensory receptors of the visceral sensory in the Afferent Division of the peripheral nervous system. This information is then sent to the central nervous system who would make the decision to throw up then send the information back to the peripheral nervous system though the efferent division to Automonic Motor Divison's  Muscle effector which would then tell your stomach to throw up.

Sensory Division

somatic sensory

Ependymal cells

axons are wrapped with a myelin sheath, a protective fatty coating that gives it glossy-white appearance

Senosry, Motor or mixed

Duramater

arachnoid

arachnoid villis

cerebral nuclei

epidural space

continuous tight junctions around endothelial cells in brain capillaries
