The nervous system is made up of nerve cells called neurons, which carry electrical impulses from extensions called axons, through the cell body, to one extension called an axon terminal. Axons that are going to the same place in the body are bundled together into nerve tracts. What neurons carry impulses away from the brain and spinal cord?
Neurons that carry impulses away from the brain and spinal cord are called motor neurons or efferent neurons.
Neurons that carry impulses away from the brain and spinal cord are known as motor neurons or efferent neurons. These neurons transmit signals from the central nervous system (brain and spinal cord) to the muscles, glands, or other effector organs, allowing for voluntary and involuntary movements and responses.
The neurons that carry impulses away from the brain and spinal cord are called motor neurons or efferent neurons. These neurons transmit signals from the central nervous system (CNS), which includes the brain and spinal cord, to the muscles, glands, and organs throughout the body.
To find this information, you can start by understanding the basic structure and function of the nervous system. The nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS includes all the other nerves in the body.
Within the PNS, there are different types of neurons, including sensory neurons and motor neurons. Sensory neurons, also known as afferent neurons, carry information from sensory organs and receptors to the CNS. On the other hand, motor neurons, or efferent neurons, transmit signals from the CNS to the muscles, glands, and organs.
In the context of your question, motor neurons specifically carry impulses away from the brain and spinal cord to signal for muscle contraction, organ function, or glandular secretion. This allows for voluntary movements, such as walking or speaking, as well as involuntary processes like digestion or heart rate regulation.
Understanding the anatomy and function of the nervous system, particularly the role of motor neurons, can help you answer questions related to the transmission of nerve impulses in the human body.
