The brain OCR A A level biology

• What are the 5 main parts of the brain

  Cerebrum, cerebellum, hypothalamus, pituitary gland, medulla oblongata
• What are the two cerebral hemispheres of the cerebrum connected by

  The corpus callosum
• What does the cerebrum control & give an example

  Higher brain functions e.g. conscious thought
• What are the different areas of the cerebral cortex

  Sensory, motor & assosciation
• What does the cerebellum control

  Balance and coordination
• What strengthens nervous pathways in the cerebellum

  Practice
• What does the hypothalamus control

  Homeostasis
• What does the hypothalamus contain

  Sensory receptors
• What type of feedback does the hypothalamus use to maintain homeostasis

  Negative feedback
• What types of regulation does the hypothalamus take part in

  Temperature regulation & osmoregulation
• What are the two lobes of the pituitary gland called

  Anterior & posterior
• What is the role of the pitutitary gland

  Works in conjunction with the hypothalamus
• What do hormones produced by the anterior lobe respond to

  Things such as stress, growth, reproduction & lactation
• What does the medulla oblongata control & give an example

  Vital processes e.g. heart rate or breathing
• How does the medulla oblongata control non-skeletal muscles

  By sending action potentials through the autonomic nervous system
