How do signals from sensory neurons reach motor neurons? (1 point)
TOOLS
• Through interneurons in the brain and spinal cord that connect sensory neurons and
motor neurons
• Motor neurons signal for the body to move the signal toward them
• Signals from sensory neurons do not get sent to motor neurons
• Signals move from dendrite to dendrite towards motor neurons
Through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons.
Signals from sensory neurons reach motor neurons through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons. The interneurons act as a bridge and transmit the signal from the sensory neurons to the motor neurons. This allows for the integration and processing of sensory information before it is sent to activate the appropriate motor response. The motor neurons then receive the signal and send instructions to the muscles or glands to produce a response, such as movement or secretion. So, the correct answer is: Through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons.
The correct answer is through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons.
To understand how signals from sensory neurons reach motor neurons, we need to have some knowledge of the nervous system and how it functions.
The human nervous system consists of two primary components: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS comprises the brain and spinal cord, while the PNS includes all the nerves that extend throughout the body.
When our body interacts with the environment, sensory neurons detect various stimuli such as touch, temperature, or pain. These sensory neurons are responsible for converting physical stimuli into electrical signals, commonly known as electrical impulses or action potentials.
Now, to transmit these electrical signals to the appropriate motor neurons, the signals must travel through the CNS. This is where the interneurons come into play. Interneurons are a specific type of neurons located in the brain and spinal cord that act as a bridge between sensory neurons and motor neurons.
When the electrical signals from sensory neurons reach the CNS, they synapse with interneurons. At these synapses, the electrical signals are transmitted from the sensory neurons to the interneurons. The interneurons then process and integrate this information before relaying it to the appropriate motor neurons.
Motor neurons are responsible for initiating and controlling voluntary and involuntary movements in our body. Once the interneurons in the CNS receive and process the information from sensory neurons, they send signals to the motor neurons through synapses. These signals mostly travel in the form of electrochemical signals.
The motor neurons then transmit the signals from the CNS to the target muscles or glands, instructing them to perform the desired action. This entire process happens incredibly fast, allowing us to react to different stimuli promptly.
In conclusion, signals from sensory neurons reach motor neurons through interneurons in the brain and spinal cord. These interneurons act as a connection between the sensory and motor pathways, allowing for the transmission of signals and enabling the coordination of movements in response to sensory input.
