PSYB64H3 Chapter Notes - Chapter 2: Central Nervous System, Dura Mater, Posterior Cerebral Artery
Document Summary
2 | the anatomy and evolution of the nervous system. Anatomical directions and planes of section rostral/anterior: toward the head end of the animal caudal/posterior: located toward the tail end of the animal. E. g. , dog"s ears caudal to its nose but rostral to its shoulders figure 2. 1, p. 28. Anatomical direction differ in ppl vs. animals on four legs. 90 degree angle to the dorsal parts of the spinal cord ipsilateral: structures are on same side of the midline contralateral: if structures are opposite sides of midline. Midline: imaginary line that divides us into approximately equal halves. Medial: structures close to midline lateral: structures to side of midline. Proximal and distal usually use to refer to limbs figure 2. 2, p. 29: coronal sections (aka frontal sections): divide brain from front to back, sagittal sections: parallel to midline, showing side view of brain structures.
