When drugs alter neuronal function, behavioral symptoms may be relieved, wors-ened, or produced. Thus, this chapter briefly describes the structure and function of normal neurons as a basis for understanding psychiatric disorders and their treatments.
16 sty 2024 · Sensory neurons (sometimes referred to as afferent neurons) are nerve cells that carry nerve impulses from sensory receptors toward the central nervous system and brain. When these nerve impulses reach the brain, they are translated into ‘sensations’, such as vision, hearing, taste, and touch.
24 lip 2023 · Structure and Function. Neurons are unique in their ability to receive and transmit information. Neurons are characterized by the long processes which extend out from the cell body or soma. Dendrites receive afferent signals. Axons carry efferent signals.
3 sie 2024 · Different types of neurons include sensory, motor, and interneurons, as well as structurally-based neurons, which include unipolar, multipolar, bipolar, and pseudo-unipolar neurons. These cells coordinate bodily functions and movement so quickly, we don't even notice it happening.
Efferent neurons (motor neurons): these direct information away from the brain towards muscles and glands. Afferent neurons (sensory neurons): these transmit information to the central nervous system from sensory receptors. Interneurons: found in the central nervous system, these pass information between motor neurons and sensory neurons.
Sensory neurons are found in receptors such as the eyes, ears, tongue and skin, and carry nerve impulses to the spinal cord and brain. When these nerve impulses reach the brain, they are translated into ‘sensations’, such as vision, hearing, taste and touch.
