Upper motor neuron cell bodies are situated in the motor cortex and project axons via the corticospinal tracts to the spinal cord. There they synapse in the anterior horn with lower motor neurons, which project axons via peripheral nerves that then contact muscle fibres at the neuromuscular junction. Lower motor neurons originating in the brain stem that control speech and swallowing (bulbar motor neurons), and lower motor neurons that originate in the spinal cord that control limb and respiratory muscles, may both be affected. Damage to various combinations of upper and lower motor neurons occurs in human amyotrophic lateral sclerosis.
What else can I help you with?
Is your spinal cord part of your immune system?
No, the spinal cord is not part of the immune system. It is primarily a component of the central nervous system, responsible for transmitting sensory and motor signals between the brain and the rest of the body. The immune system is a separate system that protects the body from infections and diseases.
What system consist of sensory and motor neurons associated with voluntary actions?
The somatic nervous system consists of sensory and motor neurons that are associated with voluntary actions. Sensory neurons transmit sensory information from the body to the central nervous system, while motor neurons transmit signals from the central nervous system to muscles to initiate movement. This system allows for conscious control over skeletal muscle movement.
The peripherral nervous system has sensory nerve cells and motor nerve cells?
Yes, the peripheral nervous system consists of sensory nerve cells that transmit sensory information from the body to the central nervous system, and motor nerve cells that transmit signals from the central nervous system to the muscles and glands to elicit a response.
How does motor impulse move througout the body?
Motor impulses travel through the body via the nervous system, primarily through motor neurons. When a signal is initiated in the brain or spinal cord, it travels down the axon of the motor neuron, which extends to the target muscle. At the neuromuscular junction, the impulse triggers the release of neurotransmitters, causing muscle fibers to contract and produce movement. This process allows for coordinated actions and responses throughout the body.
What part of the body does the plexus serve?
motor and sensory needs of the muscles and skin of the limbs body
What carries instructions from the nervous system to the body?
Motor neurons
What carries instructions from the central nervous system to the body?
Motor neurons
What function do the motor neurons play in the nervous system?
Motor neurons send messages from the brain or spinal cord to the body.
Sensory neuron is to motor neuron as?
Sensory neuron is to motor neuron...as feedback system is to control system. The motor neurons send signals from the brain to control the body. The sensory neurons send signals from the body back to the brain.
What system controls the body's response to change in its internal and external enviorment?
Motor neurons of the nervous system are what innervate muscles and glands.
What carries mssages from the central nervous system to other parts of the body?
peripheral nervous system
The sensory and motor nerve fibers that go from the brain and spinal cord to all parts of the body makeup which system?
Peripheral nervous system.
All nerves and neurons that are not contained in the brain and spinal cord but that run through the body itself are in the system?
The nerves and neurons that run through the body outside the brain and spinal cord make up the peripheral nervous system. This system transmits signals between the central nervous system and the rest of the body, allowing for sensory input and motor output. The peripheral nervous system includes sensory and motor neurons that control voluntary and involuntary bodily functions.
Structure capable of responding to motor impulse?
The musculoskeletal system is the structure in the body that responds to motor impulses. This system includes muscles, bones, and joints that work together to produce movement in response to signals from the nervous system. Muscle fibers contract in response to motor impulses sent by the nervous system, leading to movement and coordination.
What is the name of a neuron that transmits a neural impulse from the central nervous system through the spinal cord to a muscle?
The neuron that transmits a signal from the nervous system to an effector is a motor neuron.
How does the system interact with other systems in your body?
the nervous system consists of neurons. these neurons receive and transfer messages and help the nervous system to interact with other systems in our body. also the body has receptors, effectors, sensor and motor nerves which helpin the process of interaction.
What is a neroun that carries impulses away from the central nervous system to the body parts that react?
They are called as motor neurons.
