27
cranial cavity
formed by cranial bones and contains brain
28
vertebral canal
formed by vertebral column and contains spinal cord and the beginnings of spinal nerves
29
thoracic cavity
chest cavity (contains pleural and pericardial cavities and mediastinum)
30
pleural cavity
each surrounds a lung; the serous membrane of each pleural cavity is the pleura
31
pericardial cavity
surrounds the heart; the serous membrane of the pericardial cavity is the pericardium
32
mediastinum
anatomical region in the central portion of the thoracic cavity between the medial walls of pleural cavities;
extends from sternum to vertebral column and from first rib to diaphragm;
contains all the structures of the thoracic cavity other than the lungs (heart, thymus, esophagus, trachea, some large blood vessels)
33
abdominopelvic cavity
subdivided into abdominal and pelvic cavities
34
abdominal cavity
contains stomach, spleen, liver, gallbladder, small intestine, most of large intestine;
serous membrane of abdominal cavity is the peritoneum
35
pelvic cavity
contains urinary bladder, portions of large intestine, and internal organs of reproduction
36
Within the thoracic cavity:
-pericardial cavity (fluid-filled space that surrounds the heart)
-pleural cavity (two fluid-filled spaces that surround each lung)
37
What is the central part of the thoracic cavity between the lungs (extends from the first rib the diaphragm)?
mediastinum
38
Diaphragm
-separates the thoracic cavity from the abdominopelvic cavity
-major muscle of respiration by contracting rhythmically
39
Two portions of the abdominopelvic cavity:
-abdominal cavity (stomach spleen, liver, gallbladder, small and large intestines)
-pelvic cavity (urinary bladder, internal organs of reproductive system, portions of large intestine)
40
pleura
serous membrane of the pleural cavities
41
visceral pleura
clings to the surface of the lungs
42
parietal pleura
lines the chest wall
43
pericardium
serous membrane of the pericardial cavity
44
visceral pericardium
covers the heart
45
parietal pericardium
lines the chest wall
46
peritoneum
serous membrane of the abdominal cavity
47
visceral peritoneum
covers the organs
48
parietal peritoneum
lines the abdominal wall
49
mesentery
membrane that attaches organs to the body wall
50
Abduction
lateral movement away from the mid-line of the trunk in the frontal plane
(ex. raising arms or legs to the side horizontally)
51
Adduction
movement medially toward the mid-line of the trunk in the frontal plane
(ex. lowering arm to side or thigh back to anatomical position)
52
Flexion
bending movement that results in a decrease of the angle in the joint by bringing bones together, usually in the sagittal plane
(ex. elbow joint when hand is drawn towards shoulder)
53
Extension
straightening movement that increases the angle in a joint by moving bones apart, usually in the sagittal plane
(ex. elbow joint when the hand moves away from the shoulder)
54
circumduction (circumflexion)
circular movement of a limb that delineates an arc or describes a combination of flexion, extension, abduction, and adduction
(basically a limb moves in a circle)
(ex. shoulder joint or hip joint move in circular fashion around a fixed point clockwise or counterclockwise)
55
diagonal abduction
movement by a limb through a diagonal plane away from the mid-line of the body
(ex. tennis backhand, starting down and moving up across the body)
56
diagonal adduction
movement by a limb through the diagonal plane towards and across the mid-line of the body
(ex. throwing a ball, starting up and moving down across the body)
57
External rotation (lateral rotation)
rotary movement around the longitudinal axis of a bone away from the mid-line of the body, occurs in a transverse plane of motion
58
internal rotation (medial rotation)
rotary movement around the longitudinal axis of a bone toward the mid-line of the body, occurs in transverse plane
59
Eversion (foot)
turning the sole of the foot outward in the frontal plane, abduction
(ex. weight on inner edge of foot)
60
Inversion (foot)
turning the sole of the foot inward or medially in the frontal plane; abduction
(ex. weight on outer edge of the foot)
61
Dorsal flexion (dorsiflexion) (foot)
flexion movement of the ankle that results in the top of the foot moving toward the anterior tibia in the sagittal plane
62
Plantar flexion (foot)
Extension movement of the ankle that results in the foot and/or toes moving away from the body in the sagittal plane
63
Pronation (hand)
a position of the hand with the palm faced down
64
Supination (hand)
a position of the hand with the palm faced up
65
Elevation (Shoulder Girdle or Jaw)
Superior movement of the shoulder girdle or jaw in the frontal plane
(ex. shrugging shoulders or closing your mouth)
66
Depression (Shoulder Girdle or Jaw)
Inferior movement of the shoulder girdle or jaw in the frontal plane
(ex. returning to normal position from shoulder shrug or opening your mouth)
67
Horizontal Abduction (shoulder joint or hip)
movement of the humerus or femur in the horizontal plane away from the mid-line of the body
68
Horizontal Adduction (shoulder joint or hip)
movement of the humerus or femur in the horizontal plane towards the mid-line of the body
69
Dorsal flexion (dorsiflexion) (hand)
extension of the wrist with the dorsal or posterior side of the hand (back hand) moving toward the posterior side of the forearm
70
Palmar flexion (Hand)
flexion of the wrist with the anterior side of the hand (palm) moving toward the anterior side of the forearm
