Document Summary
Most brains structures are common amongst all mammals. 100 years ago lorente de no, made the first detailed description of a brain (mouse brain through a microscope) *these descriptions of brain means the part is located towards the above body parts. Sagittal- hotdog cut, across mid-line length of brain. Nervous system is symmetrical (left and right side) Ipsilateral: structures that lie on the same side of brain. Contralateral: structures that lie on opposite sides of brain. Bilateral: structures that lie on both of each side of the brain. Afferent: movement toward brain (central nervous system) example: sensory info to brain. Efferent: movement away from brain (peripheral nervous system) motor pathway to body. Humans stand upright, whereas animals tend to have quadruped posture likewise brain has similar spatial orientation, but not spinal cord. Dorsal and ventral in quadrupeds= anterior and posterior in humans. Damaged by stroke in a patient = reduced motor ability.
