Document Summary

Lecture 8-9 nervous system: anatomical orientation, rostral (beak-side) vs. caudal (tail-side, dorsal (back) vs. ventral (belly, three planes of cross-section sagittal (left/right), coronal (front/back), horizontal (top/bottom) Nerves: central nervous system, brain, main parts. Die(cid:374)(cid:272)ephalo(cid:374) (cid:858)(cid:271)et(cid:449)ee(cid:374)-(cid:271)rai(cid:374)(cid:859) lies (cid:271)et(cid:449)ee(cid:374) the (cid:271)rai(cid:374) ste(cid:373) and the cerebrum. It is composed of two main sections, the thalamus and the hypothalamus, and two endocrine structures, the pituitary and pineal glands; contains the centre for homeostasis. These folds are clinically important as herniations might occur. Arachnoid membrane loosely tied to inner membrane, leaving a subarachnoid space between the two layers. Pia mater (delicate mother) dips down into all the sulci; inseparable from the brain; arteries that supply blood to the brain are associated with this layer. Subarachnoid space cerebrospinal fluid bathes and cushions the brain. The choroid plexus is selective, which makes the composition of cerebrospinal fluid different from that of the plasmas.
