Document Summary
Average adult brain weighs ~3lbs (1. 4kg: size and mass varies proportionately . Although representing only 2% of the body weight, it receives: 15% of the cardiac output, 20% of total body oxygen consumption, 25% of total body glucose utilization. Embryology of the brain: the cns begins as a neural tube, the lumen of the tube (neurocoel) is filled with fluid, in the fourth week of development, the cephalic area of the neural tube enlarges to form: Prosencephalon eventually develops to form: telencephalon. Mesencephalon: does not subdivide, becomes the midbrain. Rhombencephalon eventually develops to form: metencephalon. Forms the pons and cerebellum: myelencephalon. Figure 16. 1 development of the human brain. Ectoderm forms outside of body: skin and. Mesoderm: in between, muscle and tissue. Neural groove: neural fold, 20 days. All of these eventually form the brain cells. Ball in the center of the brain. Gray matter: neuron cell bodies and their associated dendrites, unmyelinated axons, form nuclei.
