What makes a nerve cell good at its job?
The nerve cell is good at its job because it is very long, and is branched out across the body. It is also well insulated so that electrical impulses can pass quickly to the Central Nervous System.
What is an alternative term for an axon?
Dendrites: Unlike most axons, they receive signals from other neurons and pass the messages to the cell body of the neuron. Axons transmit impulses away from the cell body toward the axon endings/ terminals
What is the Most abundant positive electrolyte in extracellular fluid?
Sodium ion is the most concentrated ion in the extracellular fluid.
The nerve that innervates the abductor pollicus brevis in most people is called?
The nerve that innervates the abductor pollicis brevis in most people is the median nerve.
Why is amiltriptyline prescribed for ulnar neuritis?
Amitriptyline may be prescribed for ulnar neuritis to help manage nerve pain, reduce inflammation, and improve sleep. It can also help with symptoms such as tingling, numbness, and weakness associated with the condition. However, it is important to consult with a healthcare provider to determine the most appropriate treatment plan for ulnar neuritis.
What fibers are the most rapid nerve impulses conducted on?
These are nerves in animals. They include central and peripheral; peripheral include somatic and autonomic.
What part of the brain routes nerve impulses from your senses?
Most nerve impulses from our senses are routed through the: Thalamus-
Most nerve impulses from our senses are routed through the?
Most nerve impulses from our senses are routed through the thalamus before being relayed to the appropriate regions in the brain for processing. The thalamus acts as a relay station for sensory information, helping to regulate which signals are sent to the cortex for further analysis.
Which of the following would most likely occur if the vagus nerve was damaged?
development of a rapid heart beat
How do nerve cells differ from other types of cells in the body?
Nerve cells, also known as neurons, differ from other cells in the body because they are specialized for transmitting electrical signals and communication within the nervous system. Unlike most cells, nerve cells have long extensions called axons and dendrites that allow them to send and receive signals from other neurons. Additionally, nerve cells have a unique ability to generate and propagate action potentials, which are electrical impulses that allow for rapid communication between cells.
What does neuron d0?
A neuron is a single unit of nerve fiber. Most neurons jobs are to allow chemical and electrical impulses to pass from one part of the body to the other. Neurons in the brain function the same way, sending impulses back and forth.
Which inhibitory neurotransmitter is considered to be the most prevalent in the mammalian CNS?
GABA, or gamma amino butyric acid, is made from glutamate in the cells of the brain. This inhibitory neurotransmitter blocks nerve impulses.
Why is the conduction of impulses slow in autonomic nervous system?
Because there is no need for a fast transmission, in most cases, of the chemical messengers (hormones). Therefore, the nerve cells are unmyelinated and send their signal in a continuous transmission.
What structures would be most abundant in white matter?
In white matter, the most abundant structures are myelinated nerve fibers, which are composed of axons bundled together with their protective myelin sheaths. These nerve fibers facilitate rapid transmission of signals between different regions of the nervous system.
What makes a nerve cell good at its job?
The nerve cell is good at its job because it is very long, and is branched out across the body. It is also well insulated so that electrical impulses can pass quickly to the Central Nervous System.
