Distinguish between posterior and anterior and identify their subdivision and representative organ found in each side
Posterior and anterior are anatomical terms used to describe the relative positions of structures within the body.
Posterior refers to the back side or rear portion of the body or structure. It is the opposite of anterior.
The subdivision of the posterior side is called the posterior compartment. It mainly consists of the back muscles, including the trapezius, latissimus dorsi, and erector spinae muscles. The posterior compartment also contains the spinal cord, spinal nerves, and some blood vessels.
Anterior refers to the front side or forward portion of the body or structure. It is the opposite of posterior.
The subdivision of the anterior side is called the anterior compartment. It contains various organs, including:
1. Thoracic Cavity: This cavity contains the heart, lungs, esophagus, and major blood vessels.
2. Abdominal Cavity: This cavity contains organs such as the liver, stomach, small intestine, large intestine, pancreas, and gallbladder.
3. Pelvic Cavity: This cavity contains the bladder, rectum, and reproductive organs (uterus and ovaries in females, and prostate gland in males).
To summarize, the posterior compartment mainly contains muscular and neural structures, while the anterior compartment contains various organs related to the thoracic, abdominal, and pelvic cavities.
