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.
Compound-complex sentences are very common in English, but one mistake that students often make is to try to write them without having mastered the simple sentences, compound sentences, and complex sentences first.
