structure of brain

• cerebrum - controls voluntary actions, such as learning, memory, personality and conscious thought
• cerebellum - controls unconscious functions such as posture, balance and non-voluntary movement
• medulla oblongata - used in autonomic control for example heart rate and breathing rate
• hypothalamus - regulatory centre for temperature and water balance
• pituitary gland - stores and releases hormones that regulate many body functions
• Cerebrum

  • highly convoluted providing a large surface area to increase capacity for processing
  • split into two hemispheres
  • outer layer known as the cerebral cortex
• cerebellum

  • control of muscular movement, body posture and balance
  • receives information from the organ of balance in the ears, then relays information to the areas of the cerebral cortex that are involved with motor control
• medulla oblongata

  • contains important regulatory centres of the autonomic nervous system, these control reflex activities such as heart rate and breathing rate
• hypothalamus

  • controls most of the body's homeostatic mechanisms e.g temperature control
  • also much of the endocrine system as it controls the pituitary gland
• pituitary gland

  anterior pituitary - produces 6 hormones including FSH, which is involved in reproduction and growth hormones

  posterior pituitary - stores and releases hormones produced by the hypothalamus, such as ADH involved in urine formation
