I did this as part of my degree but couldn't answer it in any detail as would need a text book to jog my memory as its quite detailed. What I have done is given you a (very basic!)idea of what I think they are looking for where I can - hth! It is Friday night and I'm tired so bear that in mind
Describe the ultrasructure of skeletal muscle and explain how it relates to function. - think along lines of the muscle attached to the skeleton and how it enables the skeleton to move - give examples - ie lifting, bending etc
Explain the role of actin and myosin during the sliding filament theory of muscle contraction. - google sliding filament theory and that will help
Relate the structure of the neuromuscular junction to its function - look up this on google and then give an example of a function and relate how it works with respect to function
Describe the gross structure of the nervous system - text book?
Describe the structure and functions of neurones - text book?
Describe the nature of a simple nerve impluse and transmission of a nerve impulse accross a synapse. - looking along the lines of the myelin sheath, nodes of ranvier, impulses jumping from node to node to enable transmission and if it requires more detail, you need to go into the electrical aspect of it - ie Potassium, chloride shift etc
Explain the functional significance of synapses - nodes of ranvier - enable the impulses to jump from node to node, which enables the impules to travel much faster etc
Explain the mechanisms by which transmission may e affected clinically and pathologically. - go into diseases and physiologically causes which would affect nerve/muscle transmission
