Neurons have specialized structures called synapses where chemical neurotransmitters are released to transmit signals to neighboring neurons. These synapses contain presynaptic vesicles filled with neurotransmitters, as well as receptor proteins on the postsynaptic membrane that detect and respond to the neurotransmitters. This specialized structure allows for precise and rapid communication between neurons.
Nervous tissue is primarily composed of specialized cells called neurons and glial cells. Neurons are responsible for transmitting signals throughout the body, while glial cells provide support, protection, and nourishment to the neurons. This intricate network enables the nervous system to process and respond to information effectively.
The neurons that typically receive incoming stimuli are called sensory neurons. These neurons are responsible for transmitting sensory information from sensory receptors (such as those for touch, sight, sound, taste, and smell) to the central nervous system for processing. They play a crucial role in helping the body respond to environmental changes and stimuli.
A bundle of parallel neurons in the central nervous system is called a tract. Tracts are groups of axons that are organized together and carry specific types of information to different parts of the brain or spinal cord.
The retina is the layer of nerve tissue in the back of the eye that contains sensory neurons called photoreceptors. These photoreceptors, specifically rods and cones, respond to light and convert it into electrical signals, which are then transmitted to the brain via the optic nerve, allowing us to perceive visual information.

Muscle cells are called myocytes, gland cells are called secretory cells, and specialized cells that respond to neural stimuli are called neurons.

These are called efferent neurons. The one that carry impulses away are afferent. Afferent (A) are away (A).

sensory neurons
Neurons that bring in information are called sensory neurons. They are responsible for transmitting sensory information from sensory receptors to the central nervous system (CNS). Sensory neurons detect stimuli such as light, sound, touch, and temperature, converting these signals into electrical impulses for processing by the brain and spinal cord. This process allows organisms to perceive and respond to their environment.
The space between neurons is called the synapse.
The process is called neurotransmitter synthesis. It involves the conversion of precursor molecules into neurotransmitters by specific enzymes within neurons. This process is crucial for the production of neurotransmitters that are essential for communication between neurons in the brain.
