Transmission of an impulse between neurons depends primarily on?
The transmission between neurons depends on the number of neurotransmitters that are present. If there aren't enough transmitters, the impulse is not passed into the second neuron, meaning it's cut down. If there are enough, it leads to an action potential (nerve impulse) in the second neuron. The nerve system is a rather confusing, and very technical, system in the body.
When a neuron transfers an impulse to another neuron or to a muscle cell what is that location that receives the impulse called synapse dendrite receptor NextReset?
The location where a neuron transfers an impulse to another neuron or to a muscle cell is called a synapse. At the synapse, the presynaptic neuron releases neurotransmitters that bind to receptors on the postsynaptic neuron or muscle cell, facilitating the transmission of the signal. This process is crucial for communication within the nervous system and between nerves and muscles.
On which direction does an impulse go across a synapse?
An impulse travels in one direction across a synapse, from the presynaptic neuron to the postsynaptic neuron. This ensures that the signal transmission in the nervous system is unidirectional.
What is the direction of impulse for motor neurons?
Motor neurons carry impulses from the central nervous system to muscles or glands, resulting in a response such as muscle contraction or secretion of a substance. The direction of impulse for motor neurons is typically from the central nervous system (brain or spinal cord) to the target muscle or gland.
Which part of the annelid circulatory system is associated with muscles responsible for pumping blood?
the dorsal vessel
What are the subsystems of the autonomic nervous system?
The autonomic nervous system consists of the sympathetic nervous system, which prepares the body for fight or flight responses, and the parasympathetic nervous system, which promotes rest and digestion.
How do nerve axons enhance speed of nerve impulse transmission?
By being wrapped in myelin sheaths, produced by Schawann cells in the peripheral nervous system and oligodendrocytes in the central nervous system.
What happens to momentum when an impulse acts on a system?
Strictly speaking, you would say that a force acts on a system and the impulse of that force corresponds to the change in momentum of the system due to the action of the force. More mathematically, the impulse of a force is defined as the integral of that force with respect to time over the time period that the force acts.
What organs are in the muscular system?
The muscular system is comprised of skeletal muscles, tendons, and associated connective tissue. Organs such as the heart and smooth muscles in internal organs are not considered part of the muscular system.
What is service mains in power transmission system?
A 'service mains' is not associated with an electricity 'transmission' system, but with a low-voltage 'distribution' system. The service mains is the name given to the cable that connects a building to the low-voltage mains supply.
Which organ system are involved in movement?
The musculoskeletal system, which includes bones, muscles, and joints, is primarily responsible for movement in the body. The nervous system plays a crucial role in initiating and coordinating movement through the transmission of signals from the brain to muscles. Additionally, the cardiovascular system helps deliver oxygen and nutrients to muscles during movement to support their function.
What is the adaptive features of neurone on the central nervous system?
the neuron consist of the million short dendrites that receive electric impulse to the body cell, also the long axon that takes away the electric impulse away from the cell body and also it contain the myelin sheath that helps in contraction on axon to facilitate the quick transmission of the nerve impulse
