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.
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.
A group of neurons working together is called a neuronal network or neural network. This term refers to the interconnected network of neurons that communicate and collaborate to process and transmit information in the brain.
feature detectors-apexA synapse makes an input to the neutrons that analyze visual input and respond to the specific things.
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).

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.
interneurons also called central or association neurons
Neurons possess the property of excitability, which allows them to respond to changes in the environment by generating and transmitting electrical signals called action potentials. This excitability is facilitated by the presence of specialized ion channels in their membranes, enabling them to detect stimuli and convert them into electrical impulses. Additionally, the synaptic connections between neurons facilitate communication and integration of information, allowing them to react to various environmental changes.
