A
  • Anatomical Position- a common visual reference point
    Person stands erect with feet together and eyes forward; Palms face anteriorly with the thumbs pointed away from the body
22
Q

What is the Axial Region?

A

the main axis of the body; composed of the
head, neck, trunk, thorax, abdomen, pelvis, and perineum (region between the anus and external genitalia)

23
Q

What is the Appendicular Region?

A

the limbs

24
Q

Superior (cranial/rostral)

A

toward the head end or upper part of a structure or body; above

25
Q

Inferior (caudal)

A

away from the head end or toward the lower part of the structure/body; below

26
Q

Anterior (ventral)

A

toward or at the front of the body ; in front of

27
Q

Posterior (dorsal)

A

toward or at the back of the body; behind

28
Q

Medial

A

toward or at the midline of the body; on the inner side of

29
Q

Lateral

A

away from the midline of the body, on the outer side of

30
Q

Intermediate

A

between a more medial and lateral structure

31
Q

Proximal

A

toward or nearest the trunk or the point of origin of a part (example, the proximal end of the femur joins with the pelvic bone) (close to origin)

32
Q

Distal

A

away from or farthest from the trunk or the point or origin of a part (example, the hand is located at the distal end of the forearm)(far from origin)

33
Q

Superficial (external)

A

toward or at the body surface; more external

34
Q

Deep (Internal)

A

away from the body surface; more internal

35
Q

Coronal (frontal) plane

A

lies vertically and divides body into anterior and posterior parts (down the cranium)

36
Q

Median (mid-sagittal) plane

A

Specific sagittal plane that lies vertically in the midline

37
Q

Transverse Plane

A

runs horizontally and divides body into superior and inferior parts

38
Q

What is Bilateral Symmetry?

A

the left half of the body is essentially a mirror image of the right half

39
Q

What is the Dorsal Cavity comprised of?

A

The cranial cavity and the vertebral (spinal) cavity

40
Q

What is the ventral cavity? What is it comprised of?

A

the more anterior and larger of the closed body cavities
The ventral cavity has two main divisions: 1) Thoracic cavity and the 2) Abdominopelvic cavity

41
Q

What is the Thoracic Cavity?

A

the right and left pleural cavity (cavities that contain the lungs) and the Mediastinum

42
Q

What is the Mediastinum

A

contains the heart surrounded by the pericardial cavity, esophagus and trachea

43
Q

What is the Abdominopelvic cavity? What is it comprised of?

A

divided into two parts, the abdominal cavity and the pelvic cavity
Abdominal Cavity - contains the liver stomach kidney and other organs.
Pelvic Cavity- contains the bladder, some reproductive organs, and rectum

44
Q

What are Serous Membranes? And name them

A

line and enclose several body cavities, known as serous cavities, where theysecrete a lubricating fluid to reduce friction from muscle movements

Pleura Membrane (lung)
Pericardium Membrane (heart)
Peritoneum Membrane (Abdominopelvic viscera)

45
Q

What are the two types of serous membranes?

A

Parietal serosa and visceral serosa.

46
Q

What do partietal serosa do?

A

line the body cavities

47
Q

What does the visceral serosa do?

A

line the outer part of the organs within the body cavity.
