electric
the receptor detects the stimulus and the sensor neurone sends it to the CNS (central nervous system
Pressure receptors in the skin pick up the stimulus. It passes along a sensory neurone to the central nervous system. Within the CNS it is transferred to the cerebral contex via an association neurone, relay neurone.
Sensory receptors detect stimuli and transmit that information to the integrating center in the nervous system, such as the brain or spinal cord. The integrating center processes the incoming signals and coordinates an appropriate response, which is then carried out by the effector organs.
A reflex is an automatic response, that protects the organism from a harmful stimulus. The receptors detect a stimulus which generates a nerve impulse along the sensory neurone to the Central Nervous System (CNS). The CNS decides the appropiate response to the stimulus. The nerve impulse then travels across a synapse to the relay neurone, across another synapse to the motor neurone to the effector. This is normally a muscle or an organ which moves or responds to bring about a response appropiate to the 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.
# Motor neurones have cell bodies inside the Central Nervous System (CNS) whilst in sensory neurones the cell body is located outside of the CNS # Motor neurones transmit impulses from the CNS to the effector which brings about a response to the situation, sensory neurones transmit impulses from to the CNS from the receptor. # Sensory neurones transmit impulses as a result of external stimuli such as pressure, light, temperature etc. Motor neurone transmit impulses passed along the CNS to the effector.
The thalamus
Carried Along was created in 2000.
The nervous system, specifically the sensory organs such as the eyes, ears, skin, nose, and tongue, transmit information to the brain. Signals, in the form of electrical impulses, travel along nerves to deliver sensory information to the brain for processing.
Sensory impulses are typically in the form of electrical signals that travel along nerve fibers from sensory receptors to the brain or spinal cord. These impulses carry information about sensations such as touch, temperature, pain, and pressure. The brain then processes these impulses to generate a conscious perception of the sensory input.
Receptor → Sensory Neuron → Associative Neuron→ Motor division →Effectors
Sensory stimuli are transmitted to the brain through specialized sensory receptors that convert environmental signals into electrical impulses. These impulses travel along sensory neurons, entering the central nervous system and reaching specific areas of the brain, such as the thalamus and sensory cortices. Here, the brain processes and interprets the information, allowing us to perceive and respond to our surroundings.
