Document Summary
If you look at the r spike, and time in between them the rhythm is quite erratic. We see a decrease sv in individuals with concussions therefore increasing hr. Athletes who are working at higher intensities while still experiencing concussive symptoms can clearly be a problem. Head snaps in one direction actually stretches the nerves (axon) Buildup of tau over time is toxic to axon. Over time repeated concussion victims are no longer able to propagate aps and therefore lose executive function. Ach binds to receptors on na channels to open them. Causes na to rush in and generate ap on the sarcolemma. The sr functions to uptake calcium from the sarcoplasm and to release calcium into the sarcoplasm to initiate contraction and sequester it during relaxation. Extensive network of tubular channels (ii) to myofibrils. Each tubule terminates in a saclike vesicle that stores ca.
