peristalsis
ventilation
What is the function of the Hypothalamus?
Regulatory centre.
Homeostasis
controlling behaviour
monitoring the composition of blood plasma
What is the function of the pituitary gland?
stores and release hormones
What is the structure of the cerebrum?
highly convoluted= increased SA
left and right half know as the cerebral hemispheres
outer layer of cerebral hemisphere= cerebral cortex
What Is the structure of the pituitary gland?
found at base of hypothalamus.
split into 2 sections
What are the two sections of the pituitary gland?
Anterior (front)
Posterior(back)
