- structure and function of the brain
- cerebellum controls unconscious functions such as posture balance and non voluntary movement
- regulates motor movements
- coordinates voluntary movements, resulting in smooth and balanced muscular activity
- pituitary glands store and release hormones that regulate many body functions
- cerebrum controls voluntary actions such as learning, memory, personalty and conscious thought
- the right hemisphere controls the muscles on the left side and vice versa
- the brain is protected by the skull; also surrounded by the protective membranes called menings
- there are five main areas in the brain and can be distinguished via the shape color or microscope structure
- medulla oblongata used in autonomic control such as heart rate breathing
- carries out and regulates life sustaining functions
- the advantage of having a central control center for the body is that communications between billions of neurons involved is much faster than if they were different control centres
- hypothalamus
- regulatory center for temp and water balance
- mid brain- portion of the CNS associated with the vision, hearing , motor control, sleep/wake , arousal (alertness) and temp, regulation
- an adult brain contains approximately billion neurons
- Brain is responsible for processing all the information collected by receptor cells about changes in the internal and external environment
- also receives and processes information from the hormonal system through molecules in the blood
- cerebellum controls unconscious functions such as posture balance and non voluntary movement
