Questions: What structures develop from the basal plates during embryonic development? Check all that are correct. Check All That Apply - Anterior and lateral horns of gray matter - Anterior part of gray commissure

The structures that develop from the basal plates during embryonic development are primarily associated with motor functions. The basal plates give rise to motor neurons and related structures in the spinal cord.

1. Anterior and lateral horns of gray matter: The answer is correct. The basal plates develop into the anterior (ventral) horns of the gray matter, which contain motor neurons that send signals to skeletal muscles. The lateral horns, present in the thoracic and upper lumbar regions, also originate from the basal plates and contain autonomic motor neurons.

2. Anterior part of gray commissure: The answer is correct. The anterior part of the gray commissure, which connects the two sides of the spinal cord, is derived from the basal plates.

3. Posterior horns of the gray matter: The answer is incorrect. The posterior (dorsal) horns of the gray matter develop from the alar plates, not the basal plates. The alar plates are responsible for sensory functions.

4. Posterior part of the gray commissure: The answer is incorrect. The posterior part of the gray commissure is associated with the structures derived from the alar plates.

In summary, the structures that develop from the basal plates are the anterior and lateral horns of gray matter and the anterior part of the gray commissure.
