Biology
| Term | Definition |
|---|---|
| Cerebrum | Largest most recognisable part of the brain. It is responsible for thought, imagination and reasoning. |
| Sensory areas | Receive impulses indirectly from receptors. |
| Somatic Neurone | carry impulses from the CNS to skeletel muscles, which are under voluntary conscious control |
| Flight or fight response | A physiological reaction in response to stress, results in increase in heart rate, blood pressure,glucose levels in the blood, and redistribution of blood from the digestive tract to the muscles.caused by activation of the sympathetic nervous system. |
| Cerebellum | controls coordination of movement and posture |
| Association areas | compare input with previous experiences in order to interpret what the input means and judge an appropriate response. |
| Autonomic Neurone | is the part of the peripheral nervous system that acts as a control system functioning largely below the level of consciousness, and controls visceral functions.The ANS heart rate, digestion, respiratory rate, salivation, perspiration. |
| Central Nervous System | The complex of nerve tissues that controls the activities of the body. In vertebrates it comprises the brain and spinal cord. |
| Medulla Oblongata | The continuation of the spinal cord within the skull, containing control centers for the heart and lungs. |
| Motor Areas | Send impulses to effectors (Muscles and Glands) |
| Sympathetic Neurone | is one of three major parts of the autonomic nervous system,It is, however, constantly active at a basic level to maintain homeostasis. |
| Peripheral Nervous System | Consists of all sensory and motor neurones that are outside the central nervous system- connecting the receptors and effectors to the CNS. |
| Hypothalamus | controls autonomic nervous system and endocrine |
| Antagonistic | when sympathetic and parasympathetic systems differ in action, opposing the other. |
| Endocrine System | the system of glands that produce endocrine secretions that help to control bodily metabolic activity. |
| Parasympathetic Neurone | To be specific, the parasympathetic system is responsible for stimulation of activities that occur when the body is at rest, especially after eating, including sexual arousal, salivation, lacrimation, urination, digestion and defecation |
| Nervous System | The network of nerve cells and fibers that transmits nerve impulses between parts of the body. |
