A&P I Lab - Key Concepts Flashcards

A set of practice questions covers lab routines, body organization, anatomical terminology, planes, cavities, serous membranes, and regional anatomy based on the lecture notes.

What is the Chemical level of organization?

Atoms bond to form molecules.

What is formed at the Cellular level?

A variety of molecules combine to form the fluid and organelles of a body cell.

What is formed at the Tissue level?

A community of similar cells forming a body tissue.

What is formed at the Organ level?

Two or more different tissues combine to form an organ.

What is formed at the Organ System level?

Two or more organs work closely together to perform the functions of a body system.

What is formed at the Organismal level?

Many organ systems work harmoniously together to perform the functions of an independent organism.

In body organization, what is the correct order from smallest to largest?

Atom → Molecule → Organelle → Cell → Tissue → Organ → Organ System → Organism.

Name five body systems listed in the lecture notes.

Examples: Integumentary, Skeletal, Muscular, Nervous, Circulatory (any five of the listed systems).

What does the term Superior (cranial) mean?

Toward the head; above.

What does the term Inferior (caudal) mean?

Toward the feet; below.

What does the term Anterior (ventral) mean?

Toward the front.

What does the term Posterior (dorsal) mean?

Toward the back.

What does the term Medial mean?

Toward the midline of the body.

What does the term Lateral mean?

Away from the midline.

What does the term Intermediate mean?

Between medial and lateral structures.

What does the term Proximal mean?

Near the point of attachment or origin.

What does the term Distal mean?

Away from the point of attachment or origin.

What does the term Superficial mean?

Toward or at the body surface.

What does the term Deep mean?

Away from the surface; toward the interior.

Name the three main body planes described.

Frontal (Coronal), Sagittal (including Midsagittal), Transverse (Horizontal).

What is the midsagittal (median) plane?

A vertical plane that divides the body into left and right halves.

What does the Cephalic region refer to?

The head region.

What does the Inguinal region refer to?

The groin region.

What region is the Umbilical region?

The region around the navel (belly button).

Which serous membranes are named for their cavities and organs?

Pericardium (heart), Pleurae (lungs), Peritoneum (abdominopelvic cavity).

What are the two layers of a serous membrane called?

Parietal serosa (lines cavity walls) and Visceral serosa (covers organs).

What is the role of serous fluid?

It fills the serous cavity and reduces friction between layers.

Which serous membrane lines the internal body cavity walls?

Parietal serosa.

Which serous membrane covers the heart?

Visceral pericardium (epicardium) covers the heart; parietal pericardium lines the cavity.

Which cavity houses the brain?

Cranial cavity (a dorsal body cavity).

Which cavity houses the spinal cord?

Vertebral (spinal) cavity (a dorsal body cavity).

What two cavities are contained within the Ventral body cavity?

Thoracic cavity and Abdominopelvic (abdominopelvic) cavity.

What are the four abdominopelvic quadrants?

Right Upper Quadrant (RUQ), Right Lower Quadrant (RLQ), Left Upper Quadrant (LUQ), Left Lower Quadrant (LLQ).

What are the nine abdominopelvic regions called?

Right Hypochondriac, Epigastric, Left Hypochondriac, Right Lateral (Lumbar), Umbilical, Left Lateral (Lumbar), Right Inguinal (Iliac), Pubic (Hypogastric), Left Inguinal (Iliac).
