6.2.2: Synaptic transmission

#6.2.2.1

The detailed structure of a synapse and of a neuromuscular junction.

#6.2.2.2

The sequence of events involved in transmission across a cholinergic synapse in sufficient detail to explain:

  • unidirectionality
  • temporal and spatial summation
  • inhibition by inhibitory synapses.
#6.2.2.3

A comparison of transmission across a cholinergic synapse and across a neuromuscular junction.

#6.2.2.4

Students should be able to use information provided to predict and explain the effects of specific drugs on a synapse.

(Recall of the names and mode of action of individual drugs will not be required.)

6.2.1
Nerve impulses
6.3
Skeletal muscles are stimulated to contract by nerves and act as effectors
