question 31
1 pts
the enteric nervous system is made up of a complex network of nerve plexuses that control the visceral effectors in the
intestinal wall.
urinary bladder.
thoracic cavity.
skeletal muscles.
question 32
1 pts
the dorsal root of each spinal nerve is easily recognized as a swelling called the
dorsal cavity.
dorsal root ganglion.
dorsal root plexus.
ventral root ganglion.

Explanation:

• Question 31: The enteric nervous system (ENS) is a division of the autonomic nervous system. It is sometimes called the "second brain" and is located in the gastrointestinal tract. Its main function is to control the visceral effectors (smooth muscles, glands, etc.) in the intestinal wall. The urinary bladder is mainly controlled by the autonomic nervous system (parasympathetic and sympathetic), but not specifically by the ENS. The thoracic cavity contains organs like the heart and lungs, which are not the primary target of the ENS. Skeletal muscles are under somatic motor control, not the ENS (which is part of the autonomic - visceral motor system).
• Question 32: The dorsal root of a spinal nerve contains sensory (afferent) neurons. The cell bodies of these sensory neurons are clustered together in a swelling called the dorsal root ganglion. The dorsal cavity is a body cavity that contains the central nervous system (brain and spinal cord). A plexus is a network of nerves (e.g., brachial plexus, lumbar plexus), not a swelling on the dorsal root. The ventral root contains motor (efferent) neurons, and there is no ventral root ganglion (motor neuron cell bodies are in the spinal cord).

Answer:

• Question 31: intestinal wall.
• Question 32: dorsal root ganglion.
