The endocrine system is composed of the following:
1) hypothalamus
2) pituitary gland
3) thyroid and parathyroids
4) adrenal glands
5) pineal gland and gonads
6) pancreas
Pituitary gland is involved in gigantism. Pituitary gland produces the growth hormone. Excessive growth hormone released by the pituitary may result to gigantism. 
The enlargement of the thyroid gland is called goiter. It is a symptom of hypherthyroidism, a condition wherein levels of thyroid hormones in the blood are highly excessive.

Answer:
Dorsal horn
Explanation:
The sensory neurons cell bodies are present in dorsal horns. The front side of spinal cord consist of two arms of it. The ventral horn is the centrally located grey matter with motor neurons cell bodies. 
The dorsal horns are located at each spinal cord levels that are four in number. The sensory nuclei is present in dorsal horns that perceive somatosensory information. The information is then transferred to midbrain and diencephalon. Thus, Interneurons receiving input from sensory neurons are located in the dorsal horn.
