Question

multiple choice question
the distal end of an axon transmits a signal to the next cell across a junction called what?
neurosoma
axon hillock
synapse
neurofibril

Explanation:

• neurosoma: It is the cell body of a neuron and not a junction for signal transmission to the next cell.
• axon hillock: It is the part of the neuron where the axon originates from the cell body. It is not a junction for signal transmission to the next cell.
• synapse: A synapse is the junction between the distal end of an axon (presynaptic neuron) and the next cell (could be a neuron, muscle cell or gland cell - postsynaptic cell). Signals are transmitted across this junction.
• neurofibril: These are bundles of cytoskeletal (intermediate) filaments in a neuron. They provide structural support and are not involved in signal transmission between cells.

Answer:

synapse
