this reflex pertains to the soles of the feet:
withdrawal
abdominal
plantar
knee jerk
question 6

at the neuromuscular junction, ___ is released into the synaptic cleft, stimulating the skeletal muscles.
nicotine
ach
potassium
sodium

Explanation:

Question 5

To solve this, we analyze each option:

• Withdrawal reflex: Involves pulling away from a stimulus, not specific to feet soles.
• Abdominal reflex: Related to the abdomen, not feet.
• Plantar reflex: Specifically pertains to the soles of the feet (e.g., the Babinski sign is part of plantar reflex assessment).
• Knee - jerk reflex: Related to the knee, not feet soles.

We analyze each option:

• Nicotine: A drug, not the neurotransmitter at the neuromuscular junction.
• Ach (Acetylcholine): Is the neurotransmitter released at the neuromuscular junction to stimulate skeletal muscles.
• Potassium: An ion involved in action potentials but not the neurotransmitter at the neuromuscular junction.
• Sodium: An ion involved in action potentials but not the neurotransmitter at the neuromuscular junction.

Answer:

C. plantar
