About the Adrenal Glands. Your two adrenal glands are small, triangular-shaped endocrine glands located on the top of each kidney. Each adrenal gland is approximately 3 inches wide, and a half inch high. Each gland is divided into an outer cortex and an inner medulla. The cortex and medulla of the adrenal gland secrete different hormones.
A complex sentence is made up of one independent clause and one or more dependent clauses. Before we arrived at school, we met up at the coffee house across the street. We met up at the coffee house across the street [independent] + before we arrived at school (dependent) = complex sentence.
In English grammar, a simple sentence is a sentence with only one independent clause (also known as a main clause). Also known as a clausal sentence. Though a simple sentence doesn't contain any subordinate clauses, it isn't always short. A simple sentence often contains modifiers.
