| Term | Definition |
|---|---|
| Cerebrum | >Largest part of the brain. >Responsible for nervous system elements associated with 'humanity' including throught, imagination and reasoning. |
| Cerebellum | >Coordiates movement and posture. |
| Medulla Oblongata | >Controls breathing movements and heart rate. >Controls action of smooth muscle in gut wall. |
| Peripheral Nervous System | >Consists of all sensory and motor neurones outside CNS. >Connects RECEPTORS and EFFECTORS to CNS. |
| Endocrine System | >A system of endocrine glands. >Controls the function of cells, tissues and organs through the secretion of hormones. |
| Sensory Areas | >Receive nerve impulses indirectly from receptors. |
| Association Areas | >Compare input with previous experiences in order to interpret what an input means and judge an appropriate response. |
| Motor Areas | >Send nerve impulses to effectors (muscles and glands). |
| Parasympathetic Neurone | >Originates in brain stem and lower part of the spinal cord. >Opposes the phisiological effects of the sympathetic nervous system. - Slows heart, constricts pupils. |
| Somatic Neurone | >Carry impulses from CNS to skeletal muscles, which are under conscious control. |
| Autonomic Neurone | >Carry impulses from CNS to cardiac muscle, to smooth muscle in the gut wall and to glands, which are NOT under conscious control. |
| Sympathetic Neurone | >Originates in spinal cord. >Opposes the physiological effects of the parasympathetic nervous system. - Speeds up heart rate, dilates pupils. |
| Hypothalamus | >Controls the AUTONOMIC nervous system and the ENDOCRINE GLANDS. |
| Fight or Flight Response | >An aspect of the effects of the hormone; ADRENALINE which says that a response will either be to run away to saftey or to fight off the threat in an instance of danger. |
| Central Nervous System | >Part of the nervous system consisting of the brain and the spinal cord. |
| Antagonistic | >Describes parts of the nervous system which OPPOSE (cancel out) the effects of one another. |
| Nervous System | >The system of nerves and nerve centres in an animal or human, consisting of different systems. |
