_________ is characterized by a loss of 50% of alpha motor neurons by the age of 60

The connecting point between a motor neuron and muscle fiber is called the

The negative membrane potential in a resting neuron is primarily due to_________

The cell membrane around a muscle fiber is called the

The two major contractile proteins found in skeletal muscle are

A potential mechanism that could contribute to central fatigue includes_________

One of the proposed mechanisms to explain the positive impact of post-activation potential on muscle performance is that low-intensity muscle contractions result in phosphorylation of myosin light chains (i.e., proteins located at the base of the myosin cross-bridge). This increased phosphorylation can increase muscle force production by
