What else can I help you with?
When the receptor have registered a the energy is converted to a electrochemical impulse?
Yes, when a receptor detects a stimulus, it triggers an electrochemical impulse to be sent along a nerve cell. This impulse travels to the brain where it is interpreted as a specific sensation or perception.
What is Sense receptor?
A sense receptor is a specialized cell or group of cells that can respond to specific stimuli in the environment, such as light, sound, temperature, pressure, or chemicals. These receptors convert the stimulus into electrical signals that can be sent to the brain for processing and interpretation, allowing us to perceive our surroundings and respond to them appropriately.
Is there any way to insert the information to the brain other than learning process?
Any stimulus that is picked up by the afferent receptor nerves bring information to the brain, then it is integrated and processed. So far, another avenue has not been found to directly insert information to the brain without it going through this process.
How do sensory receptors work?
A receptor is generally a recognition molecule situated on the surface of a cell. A receptor is a molecule that is sensitive to a particular signal and is also able to transmit information to the nucleus in order to control gene regulation. In order for a receptor to function, it must first be activated. The binding of a ligand to the receptor places the receptor in the activated state. Once the receptor is activated, it is now able to transmit signal to the interior of the cell.
What is a channel linked receptor?
A channel linked receptor transduces functions of the same protein molecule. An example of a channel linked receptor are neurotransmitters in the brain.
When the receptor have registered a the energy is converted to a electrochemical impulse?
Yes, when a receptor detects a stimulus, it triggers an electrochemical impulse to be sent along a nerve cell. This impulse travels to the brain where it is interpreted as a specific sensation or perception.
Does brain have nerve?
The nervous system is made up of three parts: the receptor, the decider, and the effector. The receptor receives an stimulus and creates an electric impulse to be sent to the brain. The brain receives this impulse and decides what to do in order to react to the stimulus. Your brain then makes a decision and sends out an electric impulse to the effector which moves the muscle or activates a gland in your body which is a reaction to the stimulus.
What does your body do reaction to a stimulus?
A Stimulus is picked up by a receptor, travels along a sensory neurone to either the spinal cord or brain, then it is processed to produce some response.
A reflex arc begins with the stimulation of a what?
A reflex arc begins with the stimulation of a sensory receptor such as those on the skin. The stimulus is then passed as an electrical impulse along sensory, relay and motor neurones (by-passing the brain) before reaching an effector orgen, like a muscle, which then responds to the stimulus.
The process of changing physical stimulus to neural stimulus is called what?
The process of changing physical stimulus to neural stimulus is called transduction. This process involves converting sensory information from the environment into electrical signals that can be interpreted by the brain.
From the time a tactile stimulus is detected by a receptor in the foot to the time the resulting nerve impulses arrive in the postcentral gyrus of the brain the impulses will have traveled over?
three
What is the first event associated with a reflex?
The first event associated with a reflex is the stimulus, which activates sensory receptors in the body. These receptors then send a signal to the spinal cord, bypassing the brain to produce a quick response from motor neurons, resulting in the reflex action.
How many functions of neurons in the nervous system?
Neurons are pathways for electrical messages to pass through. Their main function is to pass a message from one neuron to another. As a whole, they transmit these messages between a receptor (something that picks up a stimulus. A stimulus includes things such as temperature, pressure, pain etc.), the brain and an effector (something which carries out the response to the stimulus). There are three main types of neurons: Sensory neurons - receive message from receptor and transmit it to the -> Interneurons - receive message from sensory neurons and pass it on to the brain*. The brain responds and the interneurons pass the message on to the -> Motor neurons - receive message from interneurons and pass it on to an effector. *In the case of a reflex arc, where there is an unconscious response (e.g. touching a hot object) the message will bypass the brain and go straight from receptor to sensory to interneuron to motor to effector.

What is the chain of events for a conscious response starting with stimulus?
A stimulus is perceived by sensory receptors, which then send signals to the brain through the nervous system. The brain processes the information and formulates a response, which is sent back through the nervous system to muscles or glands for action. The response is then carried out, leading to a conscious reaction to the original stimulus.
Is there any way to insert the information to the brain other than learning process?
Any stimulus that is picked up by the afferent receptor nerves bring information to the brain, then it is integrated and processed. So far, another avenue has not been found to directly insert information to the brain without it going through this process.
What kind of cell detects a stimulus?
Sensory cells detect external stimuli such as light, sound, touch, taste, and smell. These cells are specialized in converting the energy from these stimuli into electrical signals that can be interpreted by the brain.
