What is the long trunk of a neuron called?
The long trunk of a neuron is called an axon. The axon is responsible for conducting electrical impulses away from the cell body to other neurons, muscles, or glands.
What part of a neuron attaches the cell body to the axon?
The part of a neuron that attaches the cell body to the axon is called the axon hillock. It is located at the base of the cell body and is responsible for integrating incoming signals to generate an action potential.
What does not belong axon terminal synaptic knob bouton axon collateral?
Bouton does not belong as it refers to a swollen region along an axon where synapses are found, while axon terminal, synaptic knob, and axon collateral are all parts of the structure of a neuron.
The long process of a neuron is called the?
Axon
What mechanism is responsible for axonal transport?
Axonal transport is mainly driven by molecular motor proteins, such as kinesin and dynein, which move along microtubules within the axon. Kinesin transports cargo towards the axon terminal, while dynein transports cargo towards the cell body. These motor proteins power the movement of various organelles, vesicles, and other cellular components along the axon.
What is the long trunk of a neuron called?
The long trunk of a neuron is called an axon. The axon is responsible for conducting electrical impulses away from the cell body to other neurons, muscles, or glands.
What does an axon end in?
An axon typically ends in small branches called axon terminals. These terminals are responsible for transmitting signals to other neurons or muscle cells through structures called synapses.
What part of a neuron attaches the cell body to the axon?
The part of a neuron that attaches the cell body to the axon is called the axon hillock. It is located at the base of the cell body and is responsible for integrating incoming signals to generate an action potential.
What substance is responsible for the white appearance of white matter?
The Myelin Sheath around the axon
Can a nerve fiber survive without its cell or its axon?
No, a nerve fiber cannot survive without its cell body or axon. The cell body provides nutrients and support to the axon, while the axon is responsible for transmitting signals. Without either of these components, the nerve fiber would no longer function.
Which part of the neuron is responsible for generating a nerve impulse?
The axon is responsible for generating and transmitting a nerve impulse. It is a long, slender projection of the neuron that carries the electrical signal away from the cell body towards other neurons or muscles.
What part of the neuron can conduct an action potential?
The axon of a neuron is responsible for conducting an action potential. This is made possible by the presence of voltage-gated ion channels along the axon membrane that allow for the propagation of electrical signals.
What are axon tips?
Axon tips are the small structures located at the end of an axon, which are responsible for transmitting electrical impulses to other neurons or cells. They contain synaptic vesicles that store neurotransmitters, which are released into the synaptic cleft to communicate with neighboring cells. Axon tips are essential for the propagation of signals in the nervous system.
What are found at the end of each axon?
Axon terminals, also called synaptic terminals or terminal boutons, are found at the end of each axon. These structures are responsible for transmitting signals to the dendrites of neighboring neurons or to a target cell. At the axon terminals, neurotransmitters are released into the synaptic cleft to facilitate communication between neurons.
What is the single extension of a neuron that carries signals to other neurons?
The single extension of a neuron that carries signals to other neurons is called an axon. The axon is responsible for transmitting electrical impulses away from the cell body to other neurons, muscles, or glands.
What is the function of the neurons axon?
The axon of a neuron transmits electrical impulses away from the cell body to other neurons, muscles, or glands. It is responsible for carrying information over long distances within the nervous system.
What does axon terminal of motor neuron release?
The axon terminal of a motor neuron releases the neurotransmitter acetylcholine. Acetylcholine is responsible for transmitting signals from the motor neuron to muscle fibers, leading to muscle contractions.
