What process occurs as specialized receptor cells in the retina respond to only some features movement colors or edges of each stimulus?
sensory reduction
What are the somatic receptors?
Somatic receptors are a specialized type of receptor located near the surface of the body. These cells detect passive types of environmental stimuli, such as temperature, air currents, and barometric pressure. The receptors transmit the information to the sensory pathways via action potentials. The sensory pathways deliver the somatic (and visceral) information to the central nervous system.
What is the connection between sensory nerves and the neurons in the brain?
Sensory nerves transmit information from sensory receptors in the body to the neurons in the brain. When sensory receptors detect stimuli such as touch, temperature, or pain, they send signals through sensory nerves to the brain. Neurons in the brain then process and interpret these signals, allowing us to perceive and respond to the sensory information.
Which neurons decide about the action for a certain stimulus?
Sensory neuron
Briefly explain the function of the nervous system?
The nervous system's ultimate function is to interpret and respond to sensory signals from the environment.The nervous system consists of two main categories:1. Peripheral Nervous System (PNS): receives sensory stimuli, passes stimulus information to CNS in the form of an electrical action potential.2. Central Nervous System (CNS): consists of brain and spinal cord; interprets signals coming from sensory stimuli in the periphery and decides appropriate response to initiate- Afferent neurons transmit sensory signals from the PNS to the CNS- Efferent neurons transmit response signals to targets in the body to respond accordingly to initial sensory stimulus.
What is a Specialized area of sensory neuron that detects a specific stimulus?
the answer to this question would be sensory receptor
What is thefunction of nerves?
transmit both sensory and motor information
What is thefunction of aspinal nerve?
transmit both sensory and motor information
Why is numbness experienced after eating puffer fish?
TTX (the poison in pufferfish) inhibits neurons that transmit sensory information to the brain. Since TTX prevents the generation of action potentials in sensory nerves, the ability of the neurons to transmit sensory information will be inhibited. This loss of sensory information would be experienced as a "numbness" in areas exposed to the toxin.
What does not use a nonspecific ascending pathway to transmit sensory information to the brain?
Arousal.

Which neurons transmit information to the brain and spinal cord?
Sensory neurons gather information and send it to your spinal cord.
What are the somatic receptors?

The receptors transmit the information to the sensory pathways via action potentials. The sensory pathways deliver the somatic (and visceral) information to the central nervous system.
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 are the very first of the three steps basic to all sensory systems?
1. Recieve stimulus 2. Transform stimulus 3. Deliver stimulus
