what are the two key muscles involved in the micturition reflex?
the diaphragm muscle and the intercostal muscles.
the trapezius muscle and the deltoid muscle.
the rectus femoris muscle and the biceps femoris muscle.
the gastrocnemius muscle and the soleus muscle.
the detrusor muscle and the sphincter muscle.

Explanation:

The micturition reflex (urination) involves the detrusor muscle (contracts to expel urine from the bladder) and the sphincter muscle (relaxes to allow urine flow). The diaphragm and intercostal muscles are for breathing, trapezius and deltoid for shoulder/back movements, rectus femoris and biceps femoris for leg movements, gastrocnemius and soleus for ankle - foot movements.

Answer:

The detrusor muscle and the sphincter muscle.
