What is a type a neuron?
Type A neurons are a classification of neurons based on their conduction velocity and function. They are typically fast-conducting neurons responsible for transmitting signals quickly over long distances in the body. Type A neurons are further subdivided into categories based on the diameter of their axons and the presence or absence of myelin sheaths.
What type of cell has a long arm?
Neurons.
Are the long extensions on nerve cells enable them to form a rigid scaffolding that gives brain tissues its structure?
No, the long extensions of nerve cells, or neurons, primarily serve to transmit electrical signals and communicate with other cells, rather than providing structural support. The rigidity and structure of brain tissue are largely provided by glial cells, which support and protect neurons. While the arrangement of neurons can contribute to the overall architecture, the scaffolding of brain tissue is more influenced by the extracellular matrix and the presence of glial cells.
How long is absolute refractory period for skeletal muscles?
The absolute refractory period for skeletal muscles is about 1 to 2 milliseconds. During this time, the muscle fiber is unable to respond to a new stimulus, no matter how strong it is. This period ensures the muscle has enough time to recover before being stimulated again.
The size and shape of neurons are the same regardless of their function?
The size and shape of neurons can vary based on their function. For example, sensory neurons have long axons to transmit signals over long distances, while interneurons have more complex branching structures to integrate signals within the central nervous system. Motor neurons also have large cell bodies and long axons to send signals to muscles or glands.

Why don't neurons have centrioles?
Neurons are post-mitotic cells, meaning they no longer divide once they are fully developed. Centrioles are organelles responsible for organizing the mitotic spindle during cell division, so neurons do not require them. Additionally, the presence of centrioles in neurons could interfere with their specialized functions, such as long-distance signaling.
How do hormones help the body respond to a harmed hormonal stimulus?
hormones help the body respond to a harmed hormonal system by giving messages to your brain in a long of period of time.
What are the long arms of neurons called?
axons
What type of cell has a long arm?
Neurons.
What determines the modality of the stimulus?
The scientist, or "operator" of the experiment, gets to determine the type of stimulus used (as long as it is within ethical bounds).
What are very long electrical cells called?
Because neurons are the only cells that can conduct electric current, answer to your question would be neurons.

While the arrangement of neurons can contribute to the overall architecture, the scaffolding of brain tissue is more influenced by the extracellular matrix and the presence of glial cells.
What are long terms and short terms affects?
long term effects are things that occur over a long period, such as testicular cancer from HGH (human growth hormone) use. Short term effects are things that occur soon after the stimulus, such the "high" from using most drugs.
Are Neurons are very long lived true or false?
false.
What does the long refractory period observed in cardiac muscle mean?
it means that no matter what stimulus is applied the cardiac muscle will not be able to contract
How long is absolute refractory period for skeletal muscles?
The absolute refractory period for skeletal muscles is about 1 to 2 milliseconds. During this time, the muscle fiber is unable to respond to a new stimulus, no matter how strong it is. This period ensures the muscle has enough time to recover before being stimulated again.
