If you go to the video with head and neck, you will have those muscles there.

1. What is Wallerian degeneration? Wallerian degeneration is the process that occurs when a nerve fiber is cut or injured. Specifically, the axon distal to the site of injury degenerates because it is separated from the cell body, which provides essential nutrients and signals for the axon's survival. This process includes: Breakdown of the axonal structure. Degeneration of the myelin sheath surrounding the axon. Phagocytosis by macrophages and Schwann cells to clear debris, preparing the area for potential regeneration. 2. What is the difference between graded potential and action potential? Graded Potential Action Potential Local changes in membrane potential. Large, uniform depolarizations of the membrane. Varies in magnitude based on stimulus strength. All-or-none response (same amplitude regardless of stimulus strength). Can be depolarizing or hyperpolarizing. Always depolarizing followed by repolarization. Occurs in dendrites or cell bodies. Occurs in the axon (initiated at the axon hillock). Does not propagate; decreases with distance. Propagates without decrement down the axon. 3. What is the difference between anterograde and retrograde axoplasmic transport? Anterograde Axoplasmic Transport Retrograde Axoplasmic Transport Movement of materials from the cell body to the axon terminal. Movement of materials from the axon terminal back to the cell body. Transports neurotransmitters, vesicles, and proteins needed at the synapse. Transports recycled materials, waste, and signaling molecules. Uses kinesin as the motor protein. Uses dynein as the motor protein. Facilitates axonal growth and synaptic function. Facilitates cellular repair and communication with the nucleus. 4. What is the all-or-none principle? The all-or-none principle states that an action potential either occurs completely or does not occur at all. Once the threshold membrane potential (-55 mV in most neurons) is reached, the neuron will fire an action potential of the same magnitude every time, regardless of the strength of the stimulus. Stimuli below the threshold do not trigger an action potential.

De Nada!

Typically they run as long as 1.5 msec and as short as 0.4 msec. Keep in mind that these times can change in different parts of the body.

Best of luck! and I'm glad you found this tutorial helpful.

Many many thanks

@@AnatomyandPhysiologyPrep you're welcome 😁

Glad it helped! Good luck with your classes.

You're very welcome!

You're welcome 😊

Thanks

Glad it was helpful!

Glad to hear that

Yes, it is!

You bet! Yes it is. The mesovarium is one that is only present in females.

How do you mean animated?
