Abdomen I: Anatomy

These flashcards encompass key concepts from the lecture on abdominal anatomy, covering plane definitions, directional terms, body cavities, and specific anatomical relationships.

What are the two approaches to studying anatomy discussed in the lecture?

Traditional approach and sectional approach.

What does a 'sectional approach' in anatomy focus on?

The anatomical relationship of all structures within a given region.

How is the body likened to a loaf of raisin bread in the lecture?

The body is imagined as a thinly sliced loaf of raisin bread, where each slice has different appearances due to the different number and position of raisins.

What does cross-sectional anatomy provide a representation of?

The positions, sizes, shapes, and relationships of structures, facilitating an appreciation for the three-dimensional organization of the body.

What is the transverse plane also known as?

Axial plane.

What does the sagittal plane divide the body into?

Left and right portions.

What is the difference between midsagittal and parasagittal planes?

Midsagittal divides the body into equal left and right halves while parasagittal divides the body into unequal left and right portions.

What does the frontal (coronal) plane separate?

The body into anterior and posterior (front and back) portions.

What are the directional terms used to describe body parts?

Right, left, superior, inferior, anterior, posterior, medial, lateral, proximal, distal, superficial, and deep.

What is the anatomical position?

A common visual reference point where a person stands erect with feet together, eyes forward, and palms facing anteriorly.

What does the dorsal cavity consist of?

Cranial cavity and spinal cavity.

What organs does the thoracic cavity contain?

Lungs and heart.

What are the two subdivisions of the ventral cavity?

Thoracic cavity and abdominopelvic cavity.

What divides the abdominopelvic cavity into four quadrants?

Imaginary lines that form a vertical and horizontal plane through the umbilicus.

What are the nine regions of the abdominopelvic cavity?

Right hypochondriac, left hypochondriac, right lumbar, left lumbar, right iliac fossa, left iliac fossa, epigastric, umbilical, and hypogastric.

What is the peritoneum?

A multilayer membrane that protects and holds the organs in place within the abdominal cavity.

What is the difference between visceral peritoneum and parietal peritoneum?

Visceral peritoneum surrounds the organs, while parietal peritoneum lines the abdominal wall.

Define retroperitoneal organs.

Organs that lie posterior to the peritoneum.

What are organs covered by visceral peritoneum called?

Intraperitoneal organs.
