Neuromuscular Junction: It is a chemical synapse formed by the contact between a motor neuron and muscle fiber. It is at the neuromuscular junction that a motor neuron is able to transmit a signal to the muscle fiber causing muscle contraction.
upsteam affects
-
the direct cause is that he went to a sketchy parlor and was infected by the needle when getting the tattoo
background info
anatomy of motor neurons
-
-
axon terminal (end of axon) and muscle fiber are separated by gel-filled space called synaptic cleft
-
-
motor end plate is the oval shaped, highly excitable region of sarcolemma in closest proximity to the axon terminal
sarcolemma is folded here, called junctional folds and contains millions of ach receptors

differences between
twitch
when something stimulates or damages a nerve, it causes the muscle fibers to contract, resulting in a twitch
-
tetany
caused by an electrolyte imbalance, most often it is low calcium levels. may also be caused by magnesium or potassium deficiency
-
exocytosis
process by which the contents of a cell vacuole are released to exterior through fusion of the vacuole membrane with the cell membrane
-
muscle response
-
-
recruitment
stimulus is sent to more muscle fibers, leading to more precise control
-
-
Clostridium tetani
produces: two exotoxins, tetanolysin, tetanospasmin

what to tell the brother
he devoloped this condition because of the fact he got a tattoo, the c tetani entered through the wound and toxicated his blood.
-
if untreated he could die because it could lead to breathing difficulties, and worse spasms
