PSYB64H3 Chapter Notes - Chapter 2: Putamen, Hypoglossal Nerve, Spindle Neuron
Document Summary
Chapter 2: functional neuroanatomy and the evolution of the nervous system. Rostral: toward the head of a 4-legged animal. Caudal: toward the tail of a 4-legged animal. Ventral: toward the belly of a 4-legged animal. Dorsal: toward the back of a 4-legged animal. Anatomical terms are relative to the animal. Neuraxis: an imaginary line that runs the length of the spinal cord to the font of the brain. The human"s 2-legges stance puts a bend in the neuraxis: in the 4-legged animal, the neuraxis forms a straight line running parallel to the ground. The dorsal parts of the animal"s brain are in line with the dorsal parts of the spinal cord. Anterior, posterios, superior, and inferior don"t change with the bending of the neuraxis. Midline: an imaginary line dividing the body into 2 equal halves. Ipsilateral: structures on the same side of the midline. Contralateral: structures on opp sides of the midline.
