PSY290H5 Chapter Notes - Chapter 2: Cerebral Cortex, Frontal Lobe, Central Sulcus
Document Summary
Chapter 2: cells and structures p. 30, 34-43: gross neuroanatomy: anatomical features of the nervous system that are apparent to the naked eye, cns: the portion of the nervous system that includes the brain and the spinal cord. The solid part of the spinal cord ends in the middle of the lower back. It is highly convoluted but is made up of 3 layers of tissue rather than the 6 layers of tissue in the cerebral cortex. Known for motor coordination and control, but also cognition, and learning: adjacent pons have many nerve fibres and important motor control and sensory nuclei. Reticular formation stretches down through the pons and ends in the medulla: the medulla marks the transition from the brain to the spinal cord. Coneys all major motor and sensory fibres to and from the body. Contains buclei that drives respiration and heart rate. It is for this region that brainstem injuries are often lethal.
