Spinal Anatomy

Epithelium of Respiratory Tract, GI, Gut

Lines the Gut and Respiratory Tract

Muscles of trunk, Genitourinary Serous Membrane, Cardiovascular System, Adrenal Cortex

All the Rest

Epidermis, Hair, Retina, Anterior Pituitary, CNS, PNS, Adrenal Medulla

Nerves and Skin

• Brain
• Spinal Cord
• Ventricles
• Retina
• Posterior Pituitary

• Cranial Nerve Ganglia
• Melanocytes
• Schwann Cells
• Meissner's and Auerbach's Plexuses
• Adrenal Medulla
• Afferent Neurons of the dorsal Root Ganglia
• Postganglionics of the ANS

• Telencephalon (CN 1):
• Cerebrum, Lateral Ventricles, Septum Pellucidum, Caudate and Lenticular Nuclei

• Diencephalon (CN 2):
• Thalamus, Epithalamus, Hypothalamus, Infundibulum, Optic Chiasm, 3rd Ventricle, Mammillary bodies

• Mesencephalon (CN 3 and 4):
• Midbrain, Cerebral Peduncles, Aqueduct of Sylvius

• Metencephalon (CN 5 thru 8):
• Pons and Cerebellum

• Myelencephalon (CN 9 thru 12):
• Medulla Oblongata, 4th Ventricle

Support cell in the blood brain barrier (glucose)

Gram mesenchyme, Macrophages (CNS clean up)

Lines ventricles and makes CNF (Ectoderm)

Makes myelin in CNS

Make myelin in the PNS

• T1 to L2
• Fight or Flight (Visceral Motor, Autonomic, Not Thinking)
• Vasoconstriction/ Central aorta
• Vasodilation/ Arterioles of muscles and Capillaries of the skin
• Erector Pilli
• Sweat Glands

• IML (Intermedial Lateral Cell Nucleus in the Spinal Cord)
• Leave the cord via white (myelinated) rami communicantes (preganglionic type B fibers)
• Synapse on STG (Sympathetic Chain Ganglion)
• Leave STG via grey (unmyelinated) rami communicantes (postganglinoic type C fibers)
• NE and EPI ( Norepinephrine and Epinephrine)

Note: One fiber does not synapse (white fiber) to the Adrenal Medulla = postganglionic fiber. Pheochromocytoma = a gray color cell tumor which causes Hypertension (HTN) - excess EPI.

• Superior Sympathetic Chain Ganglion = above C4 pupil dilation (Horner's Syndrome) [ptosis, meiosis, anhydrosis]
• Middle Sympathetic Chain Ganglion = C4-C5
• Inferior Sympathetic Chain Ganglion = C6-C8
• Stellate Ganglion = C8-T1 (Merger between Inferior Sympathetic Chain Ganglion and Upper Thoracic Ganglion)

Intellect and Association

• Frontal Lobe: Motor
• Parietal Lobe: Sensory
• Occipital Lobe: Sight
• Temporal Lobe: Hearing

Relay Station, Sensory fibers

Hunger, Thirst, Temperature Regulation, Sex, Rage, Fear

Balance and Equilibrium, Involuntary Coordination

Vasomotor, Cardiac Center, Autonomic NS

• A collection of cell bodies that lie within the white matter of the cerebrum.
• These plan and coordinate voluntary movement.
• Striatum = Putaman = large, dark, lateral = Lentiform
• Striatum = Globus Pallidus = small, pale, medial = Lentiform
• Striatum = Caudate Nucleus
• Amygdala

connect regions of the same hemisphere. Wernkes to limbic

carry impulse across the corpus callosum. Left to Right

send impulses from below to the cortex. Brain stem to cortex
