0
Section
A cut
1
Plane
When the section is made through the body wall or through an organ, it is made along an imaginary line or surface called a plane
2
Sagittal plane
Divides the body into right and left parts
3
Midsaggittal (median) plane
Divides the body into EQUAL right and left parts
4
Parasagittal plane
Divides the body into UNEQUAL left and right parts
5
Coronal (frontal) plane
A longitudinal plane that divides the body (or an organ) into anterior and posterior parts (front/back)
6
Transverse plane
Divides the body into superior and inferior parts (top/bottom)
7
Cross sections
When organs are sectioned along the transverse plane, the sections are commonly called cross sections
8
Cranial cavity
The cavity in which the brain is enclosed within the rigid skull
9
Vertebral (spinal) cavity
The cavity the spinal cord is in
10
Dorsal cavity
Included the cranial and spinal cavities
11
Abdominal cavity
The area that houses the stomach, intensities, liver, and [some] other organs
12
Pelvic cavity
The region that is partially enclosed by the bony pelvis and contains the reproductive organs (urinary) bladder and rectum
13
Abdominopelvic cavity
The cavity inferior to the diaphragm
14
Thoracic cavity
The cavity above the diaphragm
15
Ventral cavity
Made up of the thoracic, abdominal, and pelvic cavities
16
Quadrants
A scheme, used by most physicians and nurses, that divides the abdominal surface (and the abdominopelvic cavity deep to it) into 4 approximately equal regions called quadrants
17
Umbilical region
The centermost region which includes the umbilicus
18
Epigastric region
Immediately superior to the umbilical region; overlies most of the stomach
19
Hypogastric (pubic) region
Immediately inferior to the umbilical region; encompasses the pubic area
20
Iliac regions
Lateral to the hypo gastric region and overlying the superior parts of the hip bones
21
Lumbar regions
Between the ribs and the flaring portions of the hip bone; lateral to the umbilical region
22
Hypochondriac regions
Flanking the epigastric region laterally and overlying the lower ribs
23
Serous membrane (serosa)
Covers walls of ventral body cavity and organs within this cavity
24
Parietal serosa
The part of the membrane lining the cavity walls
25
Visceral serosa
Covering the external surface of the organs within the ventral cavity
26
Pericardium
Serous membrane that encloses the heart
27
Pleura
Serous membrane the encloses the lungs
28
Peritoneum
The serous lining the abdominal cavity and covering it's organs
29
Oral cavity
Commonly called the mouth, contains the tongue and teeth; also called the buccal cavity
30
Nasal cavity
Located within and posterior to the nose
31
Orbital cavity
Houses the eyes and presents them in an anterior position
32
Middle ear
Lies just medial to the ear drum- is carved into the bony skull- contain tiny bones that transmit sound
