Q

Describe the structure and function of the hypothalamus

A
  • the hypothalamus is found just beneath the middle part of the brain
  • it controls the homeostatic mechanisms
  • monitors the blood and regulates factors such as body temperature and blood water potential
  • controls much of the endocrine function of the body as it regulates the pituitary gland through hormone control
2
Q

Describe the structure and function of the cerebellum

A
  • the cerebellum is underneath the cerebrum and it also has a folded cortex
  • it’s important for muscle coordination, posture and coordination of balance
  • receives information from various senses, retins, balance organs in the inner ear, joints and spindle fibres and sends impulses to the motor areas
3
Q

Describe the structure and function of the medulla oblongata

A
  • the medulla oblongata is at the base of thr brain at the top of the spinal chord
  • controls involuntary processes such as heart rate and breathing rate
4
Q

Describe the role of the brain and nervous system in the coordination of muscular movement

A
  • the CNS (brain and spinal chord) receives sensory information and decides what kind of response is needed
  • the conscious decision to move is initiated in the cerebellum
  • neurones from the cerebellum carry impulses to the motor areas so that output to the effectors can be adjusted appropriately in these requirements

Q

Describe the structure and function of the cerebrum

A
  • the cerebrum is the largest part of the brain
  • it is divided into 2 hemispheres connected via the corpus callosum
  • the cerebrum had a thin outer layer called the cerebral cortex which is highly folded
  • the cerebrum is involved in vision, hearing, learning and thinking
