BIOC32H3 Lecture Notes - Lecture 10: Aphasia, Central Nervous System, Primary Motor Cortex
Document Summary
Diencephalon- structures include, hypothalamus, thalamus, basal ganglia, pineal and pituitary gland. Hypothalamus: controls homeostasis and behaviour e. g desire to eat and drink. Brain stem- structures include the medulla oblongata and pons. Medulla oblongata: for arousal, muscles, breathing, blood pressure regulation, pain, swallowing and vomiting. Viscera function is often integrated in the spinal cord and brain stem. Pons: for breathing, relays info between cerebellum and medulla. Cerebellum- for co-ordination of fine movement, balance and equilibrium (together with inner ear), body position and balance. Auditory cortex- receives information from the ears sound. Visual cortex- receives information from the eyes sight. Olfactory cortex- receives information from receptors in the nose smell. Gustatory cortex- receives information from the taste buds taste. Each hemisphere of the brain controls function on the opposite side of the body e. g vision, skeletal muscles, hearing. There is functional specialisation of each hemisphere (cerebral dominance)
