What is a specialized nerve endings in sensory nuerons that detect changes inside and outside the body called?
Specialized nerve endings in sensory neurons that detect changes inside and outside the body are called sensory receptors. These receptors can respond to various stimuli such as temperature, pressure, and chemicals, sending signals to the brain for interpretation.

receptors
What specialized neurons detect sensory energy from the outside world?
Receptor
What are the functions of the dentrites?
Dendrites are specialized extensions of neurons that play a crucial role in receiving and integrating signals from other neurons. They contain numerous receptors that detect neurotransmitters released at synapses, allowing for the transmission of information. By processing these signals, dendrites contribute to the overall excitability of the neuron and help determine whether an action potential will be generated. Additionally, dendrites can undergo structural changes in response to activity, which is important for learning and memory.
How do receptors detect temperature outside the body?
Receptors that detect temperature outside the body, such as in the skin, are known as thermoreceptors. These specialized nerve endings respond to changes in temperature by detecting thermal energy. When the temperature changes, thermoreceptors send electrical signals to the brain, allowing us to perceive and respond to hot or cold stimuli.
What is the area of neuron that detect a stimulus?
The area of a neuron that detects a stimulus is primarily the dendrites, which are the branching extensions of the neuron. Dendrites receive signals from other neurons or sensory receptors and transmit these signals toward the cell body. In sensory neurons, specific receptors located on the dendrites are specialized to detect stimuli such as light, sound, or touch. This initial detection is crucial for initiating the neuronal response to various environmental signals.
What type of receptor detect heat and cold?
Thermoreceptors are the type of receptors that detect heat and cold. They are specialized nerve endings located in the skin and other tissues that respond to changes in temperature.
How do protoctista detect environmental changes?
Protoctista can detect environmental changes through various mechanisms such as sensing chemical cues in their surroundings, responding to changes in light intensity, or detecting variations in temperature and pH. These organisms may also rely on specialized sensors and receptors on their cell surface to perceive changes in their environment.
Does a receptor detect change in the environment?
Yes, receptors are specialized cells or proteins that detect changes in the environment or within the body, such as changes in temperature, pressure, or the presence of chemicals. They transmit this information to the nervous system for further processing and response.
In general neural messages are received by the and transmitted by the?
In general, neural messages are received by the dendrites of a neuron and transmitted by the axon. Dendrites are specialized structures that detect signals from other neurons, while the axon carries electrical impulses away from the neuron's cell body to communicate with other neurons or target tissues. This process forms the basis of neural communication within the nervous system.
What are the recptors that detect heat snd cold called?
The receptors that detect heat are called thermoreceptors, and the receptors that detect cold are called cold receptors. These receptors are specialized nerve cells that respond to changes in temperature and send signals to the brain to interpret these sensations.
What are cell called that detect changes?
Cells that detect changes are called sensory cells or receptor cells. These specialized cells are equipped with receptors that can sense various stimuli such as light, sound, pressure, temperature, and chemicals. They transmit this information to the central nervous system for processing and response.
