Before the motor neuron cone arrives the muscle fiber‚ AChR clusters are formed in the middle section of a muscle fiber. When the growing nerve cone attaches the muscle fiber‚ Agrin activates Lrp4‚ which then binds to the receptor tyrosine kinase MuSK‚ through this binding MuSK is phosphorylated and starts to form the neural and aneural AChR clustering (Burden 2011). Morphologic differences in the pre- and/or postsynaptic part of the NMJ can be a hint of a certain disease. In the following figure

Nervous Conditions What is the meaning of this book’s title? Where does it come from? (2 lines‚ 5 points): The quote comes from Fanon’s Wretched of the Earth.

Animals have three types of muscles; skeletal‚ smooth‚ and cardiac. This lab however is only concerned with skeletal muscle. A special characteristic of skeletal muscle is their ability to contract or shorten via thin (actin) and thick (myosin) filaments (Flanagan‚2017). This gives a striated appearance which is a key distinguishing characteristic between other types of muscle (Flanagan‚2017). Skeletal muscle is also multinucleated. Skeletal muscle needs plentiful amounts of energy to be able to

NON-ASSOCIATIVE LEARNING Non-associative learning (Single-event learning) is a change in behavior due to repeatedly exposure to a single event and does not involve learning of a relationship between multiple events. It is contrasted with associative learning (e.g. classical conditioning or operant conditioning) that involves learning the associations between different events. WHAT IS HABITUATION? Habituation is the decrease of a response to a repeated eliciting stimulus that is not due to sensory

PHYSIOEX 9‚ ACTIVITY #3 Review Questions ACTIVITY #1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability

As a response to injury‚ among other factors‚ myofascia may bond to abutting structures and contract‚ which may cause adhesions. These adhesions may

In my discussion‚ the Governments of Rome and Carthage did differ in such a way that their societies were governed by two very different models. In considering The Roman Republic‚ I noted that it was formed by representatives. And the whole idea was borrowed from the Greeks as they were experimenting on democracy.

for the most part‚ the general population consists of compatibilists. Now‚ I know experimental philosophy has a problem with the use of generalizations without actual statistics‚ but throughout this paper‚ I will explain exactly why the world revolves in a generally compatibilist manner. Firstly‚ to speak of compatibilism‚ you’d have to assume that the world is deterministic‚ meaning that everything that happens from here on out‚ including human action‚ is caused by the facts of everything that has
