Question

what is the gap between the plasma membranes of a neuron that conducts an incoming signal and the cell that is going to receive the signal called?
neuromuscular junction
intercellular cleft
synapse
intercalated disc
this tissue is voluntary and has many striations

Explanation:

• First question:
• A synapse is the gap between the plasma membranes of a neuron (presynaptic neuron) that conducts an incoming signal and the cell (postsynaptic cell, which can be a neuron, muscle cell, etc.) that is going to receive the signal.
• A neuromuscular junction is a type of synapse between a motor neuron and a muscle cell, but the general term for the gap between a neuron and a receiving cell (not just muscle) is synapse.
• An intercellular cleft is a space between cells (e.g., in some epithelial tissues), but not specifically related to neuron - signal - receiving cell communication.
• An intercalated disc is a structure in cardiac muscle, not related to the neuron - cell signal - conducting gap.
• Second question:
• Skeletal muscle tissue is voluntary (under conscious control) and has many striations (due to the arrangement of actin and myosin filaments).

Answer:

• First question: C. synapse
• Second question: Skeletal muscle tissue
