Anatomical Terminology – Body Planes, Region & Cavities Flashcards
Body Plane
A body is divided into three separate planes to allow medical personnel to clearly refer to front or back, left or right, top or button regardless of the person actual position
Frontal Plane
Divide the body vertically. Create the anterior (front) and posterior (back) portions of the body
Sagittal Plane
- Divides the body into left and right sides.
- Mid-sagittal plane cuts through the exact center of the body or organ
Transverse Plane
Creates upper and lower sections of the body. Also known as a cross-section.
Body Region
Divide the body into various anatomic districts
Abdominal
Center anterior region of the trunk
Trunk
Trunk or torso is the central part of the human body from which extends the neck and limbs. The trunk includes the thorax and abdomen
Body Cavities
A fluid-filled space inside the body that holds and protects internal organs. Separated by membrane and other structures in human
Thoracic cavity
Thoracic cavity, also called chest cavity, the second largest hollow space of the body.
Abdominal Cavity
The cavity within the abdomen, the space between the abdominal wall and the spine.
The Abdominal Cavity is divided into 4 Quadrants. Name the 4
- Right Upper Quadrant (RUQ)
- Right Lower Quadrants (RLQ)
- Left Upper Quadrant (LUQ)
- Left Lower Quadrant (LLQ)
What are the Nine regions of the Abdominal Cavity?
- Right Hypochondriac Region: You’ll find organs such as the liver, gallbladder, right kidney, and portions of the small and large intestine in this region.
- Epigastric Region: This region contains portions of the liver, as well as the stomach, pancreas, duodenum, spleen, and adrenal glands.
- Left Hypochondriac Region: This contains the spleen, large/small intestines, left kidney, pancreas, stomach, and the tip of the liver.
- Right Lumbar Region: You’ll find portions of the ascending colon, small intestine, and right kidney in this region.
- Umbilical Region: Here you’ll find the duodenum, the small intestine, as well as the transverse colon.
- Left Lumbar Region: You’ll find parts of the descending colon, small intestine, and left kidney in this region.
- Right Iliac Region: Here you’ll find the appendix, cecum, ascending colon, and small intestine.
- Hypogastric Region: You’ll find the bladder, portions of the sigmoid colon, small intestine, and reproductive organs in this region.
- Left Iliac Region: You’ll find parts of the sigmoid colon, descending colon, and small intestine in this region
Cranial Cavity
This cavity house the meninges (brain)
Spinal Cavity
a continuation of the cranial cavity as it travels down the midline of the back
Pelvic cavity
inferior to the abdominal cavity, houses the bladder
