1What is neural control and coordination?
Neural control and coordination is the regulation of body activities by the nervous system.
2What are the two systems involved in coordination?
Nervous system and endocrine system are involved in coordination.
3What is a neuron?
Neuron is the structural and functional unit of nervous system.
4What are the parts of a neuron?
Cell body, dendrites and axon are the parts of a neuron.
5What is the function of dendrites?
Dendrites receive nerve impulses.
6What is the function of axon?
Axon transmits nerve impulses away from the cell body.
7What is a nerve impulse?
Nerve impulse is an electrical signal transmitted along a neuron.
8What is resting potential?
Resting potential is the potential difference across the membrane of a resting neuron.
9What is action potential?
Action potential is the electrical change that occurs during transmission of nerve impulse.
10What is synapse?
Synapse is the junction between two neurons.
11What are neurotransmitters?
Neurotransmitters are chemical substances that transmit impulses across synapse.
12Name a common neurotransmitter
Acetylcholine is a common neurotransmitter.
13What is the human nervous system divided into?
Central nervous system, peripheral nervous system and autonomic nervous system.
14What does the central nervous system include?
Brain and spinal cord form the central nervous system.
15What does the peripheral nervous system consist of?
Cranial nerves and spinal nerves form the peripheral nervous system.
16What is autonomic nervous system?
Autonomic nervous system controls involuntary actions.
17What are the divisions of autonomic nervous system?
Sympathetic and parasympathetic nervous systems.
18What is the function of sympathetic nervous system?
It prepares the body for stressful situations.
19What is the function of parasympathetic nervous system?
It helps in relaxation and conservation of energy.
20What is reflex action?
Reflex action is a quick, automatic response to a stimulus.
21What is reflex arc?
Reflex arc is the pathway followed by a nerve impulse during reflex action.
22Name the components of reflex arc
Receptor, sensory neuron, interneuron, motor neuron and effector.
23What is brain?
Brain is the main coordinating centre of the body.
24What are the three major parts of brain?
Forebrain, midbrain and hindbrain.
25What is the function of cerebrum?
Cerebrum controls voluntary actions and intelligence.
26What is the function of thalamus?
Thalamus relays sensory impulses.
27What is the function of hypothalamus?
Hypothalamus maintains homeostasis and links nervous and endocrine systems.
28What is the function of cerebellum?
Cerebellum coordinates muscular movements and maintains posture.
29What is the function of pons?
Pons regulates respiration.
30What is the function of medulla oblongata?
Medulla controls involuntary actions like heartbeat and breathing.
31What is spinal cord?
Spinal cord conducts impulses to and from brain and controls reflexes.
32What is an endocrine gland?
Endocrine gland is a ductless gland that secretes hormones.
33What are hormones?
Hormones are chemical messengers that regulate physiological processes.
34What is neuroendocrine coordination?
Neuroendocrine coordination is interaction between nervous and hormonal control.
