Sensory (afferent) neurons
What else can I help you with?
Cells called what detect changes in the environment known as stimuli?
Sensory receptors detect changes in the environment known as stimuli. These receptors are specialized cells that send signals to the brain or spinal cord in response to specific types of stimuli such as light, sound, pressure, or chemical signals.
Nerve tissue is supported by specialized cells known as?
Nerve tissue is supported by specialized cells known as glial cells or neuroglia. These cells provide structural support, insulation, and protection for the neurons in the nervous system. They also play a role in regulating the extracellular environment of neurons.
Sensory neurons are also known as?
Afferent Neurons
What is the loss of responsiveness to stimuli that convey little or no information?
The loss of responsiveness to stimuli that convey little or no information is known as habituation. This process allows organisms to filter out repetitive or non-relevant stimuli in order to focus on more important information in their environment.
What is peritricial nerve ending?
Peritricial nerve endings, also known as peritrichial receptors, are specialized sensory nerve endings that wrap around the base of hair follicles in the skin. They are sensitive to mechanical stimuli, such as touch or movement of hair, and play a role in the sensation of light touch. These nerve endings help the nervous system detect changes in the environment, contributing to the sense of touch and providing feedback about external stimuli.

What is The tendency of the brain to ignore environmental factors that remain constant is?
This tendency is known as sensory adaptation. It occurs when the brain filters out repetitive or constant stimuli to focus on new or changing information. This allows us to detect important changes in our environment rather than being overwhelmed by unchanging stimuli.
What is the ability to detect small changes of weak stimuli and large changes in stron stimuli?
This ability is known as Weber's Law, which states that the smallest change in a stimulus that can be detected is proportional to the magnitude of the original stimulus. The law suggests that the ability to detect changes in stimuli depends on the intensity or strength of the original stimulus.

What type of neuron carries information to the CNS?
Sensory neurons, also known as afferent neurons, carry information from sensory receptors to the central nervous system (CNS). These neurons transmit information about external stimuli (such as touch, sound, and light) or internal conditions (such as pain or temperature) to the brain and spinal cord.
The minimal difference between two stimuli that people can reliably detect?
The difference threshold, also known as the just noticeable difference, is the smallest change in a stimulus that can be detected by an observer. It is a measure of the sensitivity of a human's sensory system to changes in stimuli.
Which type of neurons carries impulses sense organs to the spinal cord or brain?
Sensory neurons
What cells show irritability and conductivity?
Neurons are highly irritable or excitable(responsive to stimuli). When a neuron is adequately stimulated, an electrical impulse is generated and conducted along the length of its axon. This response, called the action potential or nerve impulse, is always the same, regardless of the source or type of stimulus, and it underlies virtually all functional activities of the nervous system.The answer is NEURONS.

Peritricial nerve endings, also known as peritrichial receptors, are specialized sensory nerve endings that wrap around the base of hair follicles in the skin. They are sensitive to mechanical stimuli, such as touch or movement of hair, and play a role in the sensation of light touch. These nerve endings help the nervous system detect changes in the environment, contributing to the sense of touch and providing feedback about external stimuli.
Hot and cold stimuli are detected by?
Hot stimuli are detected by heat-sensitive receptors called thermoreceptors, while cold stimuli are detected by cold-sensitive receptors in the skin known as cold thermoreceptors. These receptors are specialized nerve endings that are able to detect changes in temperature and transmit this information to the brain to generate the sensation of heat or cold.
