The way the brain sends responses to stimuli.
sensory nerves receive messages from the brain, then sensory nerves send receptor messages, and subsequently, from the receptors send messages to stimuli. (brain - sensory nerves - receptors - impulses)
The nervous system is a coordinating system that has the task of delivering stimuli and receptors for the body to detect and respond to.
Three components are owned by the nervous system, including the following:
1. Effector: The part that responds to stimuli that have been delivered by the conductor of impulses.
2. Receptors: Receptors or impulses.
3. Conduct impulses: Treated by the nerves themselves. Nerves are composed of connecting fibers. In connecting fibers there are special cells that extend and expand, nerve cells are called neurons.
The nervous system allows living things to respond quickly to changes that occur in the outer and inner environments.
- Impulses are stimuli or messages received by receptors from the outside environment, then carried by neurons. for example: Changing from cold to hot.
- Nerve cells: the nervous system consists of nerve cells called neurons. Neurons combine to form a network to deliver impulses. A nerve cell is composed of cell bodies, dendrites, and axons.
a. Dendrites are short and branched nerve cell fibers, whose job is to receive and deliver stimulation to the cell body.
b. Cell body: the largest part of nerve cells, the task is to receive stimuli from dendrites and then forward them to axons.
c. Axons: long nerve cell fibers which are the extending cytoplasm of the cell body, functioning to accelerate the course of stimulation.
