What carries the nerve impulse from the central nervous system to an effector?
Nerve impulses are carried from the central nervous system to the effector organs (muscles or glands) by motor neurons. These motor neurons form a pathway known as the efferent pathway.
What stimuli does eyes detect?
Eyes detect light and visual information in the form of colors, shapes, and patterns. Light entering the eyes is focused by the lens onto the retina, where it triggers nerve impulses that are then processed by the brain to create the images we see.
What form of energy is used to transmit messages from one part of the body to another?
Electrical energy is used to transmit messages from one part of the body to another through the nervous system. Nerve cells called neurons use electrical signals to communicate with each other and relay information throughout the body.
What types of electromagnetic radiation do human bodies emit?
Human bodies emit various types of electromagnetic radiation, primarily in the form of infrared radiation (heat) and extremely low-frequency electromagnetic fields produced by biological processes like nerve impulses and muscle contractions. These emissions are typically very low in intensity and are a natural part of the body's functioning.
What does the optic nerve in the human eye do?
The optic nerve is responsible for carrying visual information from the eye to the brain. It transmits signals that the eye receives from light-sensitive cells to the visual cortex in the brain, where the information is processed to form images.
What afferent neurons convey information?
Afferent neurons carry sensory information in the form of nerve impulses to the central nervous system. Efferent/motor neurons carry commands to effectors such as muscles and glands.
Nerve cells that transmit nerve impulses in the form of electrochemical changes are known as?
Neurons
What does a bundle of neurons form?
A bundle of neurons is called a nerve. The neuron bundle, nerve, has afferent and efferent pathways, that means that it is like highways that are parallel to each other yet carry impulses, or traffic, in both directions.
Which type of tissue carries electrical impulses from your brain?
Nervous tissue, specifically neurons, carry electrical impulses from the brain to other parts of the body. These neurons transmit information in the form of electrical signals known as action potentials.
What are two major types of cells that form nervous tissue?
First is the neuroglia, function is to support and protect the cells of the nervous system. Second is neurons, which are responsible for conducting nerve impulses from one part of the body to another.
How is the nerve special?
Nerve cells carry impulses in the form of electrical currents, they are insulated by myelin to avoid the electrical current from 'leaking out'.
What carries the nerve impulse from the central nervous system to an effector?
Nerve impulses are carried from the central nervous system to the effector organs (muscles or glands) by motor neurons. These motor neurons form a pathway known as the efferent pathway.
What are the nerve cells that carry signals from the central nervous system to the muscles or glands?
The nerve cells that carry signals from the central nervous system to the muscles or glands are called motor neurons. These neurons transmit information in the form of electrical impulses to stimulate muscle contraction or glandular secretion.
How is the nerve cell specialized?
Nerve cells carry impulses in the form of electrical currents, they are insulated by myelin to avoid the electrical current from 'leaking out'.
What carries information throughout the body in form of electrochemical signals called impulses?
Neurons
What is the Function of Neurons?
Sensory neurons relay information from sense organs, motor neurons carry impulses to muscles and glands, and inter-neurons transmit impulses between sensory and motor neurons. A typical neuron consists of dendrites (fibres that receive stimuli and conduct them inward), a cell body (a nucleated body that receives input from dendrites), and an axon (a fibre that conducts the nerve impulse from the cell body outward to the axon terminals). Both axons and dendrites may be referred to as nerve fibres. Impulses are relayed by neurotransmitter chemicals released by the axon terminals across the synapses (junctions between neurons or between a neuron and an effector cell, such as a muscle cell) or, in some cases, pass directly from one neuron to the next. Large axons are insulated by a myelin sheath formed by fatty cells called Schwann cells. Bundles of fibres from neurons held together by connective tissue form nerves.

The cells that transmit nerve impluses in the nervous system are?
The cells that transmit nerve impulses in the nervous system are called neurons. Neurons are specialized cells that are capable of generating and conducting electrical signals throughout the body. They form the basic building blocks of the nervous system and are essential for communication between different parts of the body.
