MCAT Endocrine System

MCAT Endocrine System
Exocrine glands release enzymes to the surrounding tissue through ducts. Endocrine glands release hormones directly into bodily fluids (ie blood).

Hormones are three types of chemicals:

1. Peptide hormones

2. Steroid hormones

3. Tyrosine Derivatives

Learn the different hormones and their function by the gland they are released from.

Anterior Pituitary
The anterior pituitary releases peptide hormones.

hGH (Human Growth Hormone): Affects all cells in the body. Initiates growth through increased amino acid transport through the cell membrane, increases translation and transcription and decreasing the breakdown of proteins and amino acids.

ACTH (Adrenocorticotropic Hormone):

TSH (Thyroid Stimulating Hormone):
