Answer:
Nervous system and endocrine system are the systems that control and co-ordinate various functions in the body.
The responses of the nervous system can be classified as reflex, voluntary and involuntary actions.
The human nervous system is studied under 2 divisions -the Central Nervous System and the Peripheral Nervous System.
The Central Nervous System consists of brain and spinal cord. The peripheral nervous system is further divided into Somatic Nervous System and Autonomous Nervous System.
The Autonomic Nervous System has 2 parts- Sympathetic and Parasympathetic, which cause physical reactions opposite to each other.
Nerve Cell is the structural and the functional unit of nervous system.
Synapse is a gap across which signals are transmitted from one neuron to the other.
Hormones produced in one part would move to another part to achieve the desired effect.
A feedback mechanism regulates the action of hormones.
Directional movements in plants in response to specific stimuli like light, chemicals, etc; are called tropic movements.
Plant hormones are usually growth effectors or inhibitors. Some growth effectors are Auxins and Gibberellins while inhibitors are like Abscisic acid.
All our functions are carried out by an effort of several systems working together. All living organisms respond to stimuli.
The ability to react to particular stimuli in a particular situation must be of great importance in ensuring the survival of an organism.
Responses are brought about by rapid changes in some muscles and such changes are usually related to changing stimuli.
Each nerve cell consists of a head, dendrites and Axon.
Nervous system contains about 10 billion of them which communicate with each other in a specific manner.
Afferent neurons are also called as sensory nerves. Efferent neurons are also called motor nerves.
Association nerves link together the afferent and efferent nerves.
A single pathway going up to the spinal cord from detectors and returning to effectors is a reflex arc.
Most actions of our body are controlled together by voluntary and involuntary pathways.
