- Sections of the Brain
- CEREBRUM:
- Cerebral cortex is sub-divided into sensory areas, motor areas and association areas.
- Sensory areas: Receive impulses indirectly from the receptors.
- Motor areas: Send impulses to effectors (muscles and glands).
- Association areas: Compare input with previous experiences in order to interpret what the input means and judge an appropriate response.
- CEREBELLUM:
- Involved in coordinated motor response. Neurones carry impulses to the motor areas so motor output to effectors can be adjusted.
- Plays a key role in coordinating balance, fine movement and posture.
- Processes sensory info from: The retina, balance organs in ear, spindle fibres in muscles.
- HYPOTHALAMUS:
- Controls the autonomic nervous system and endocrine glands. Also controls most of the body's homeostatic mechanisms.
- Sensory input from temperature receptors and osmoreceptors received by the hypothalamus and leads to initiation of automatic responses that regulate body temp and blood water potential.
- MEDULLA OBLONGATA:
- Controls smooth muscle action i n gut wall, controls breathing movements and heart rate.
- Controls non-skeletal muscles (cardiac and involuntary) - in control of autonomic nervous system. Cardiac centre and respiratory centre found here.
- CEREBRUM:
