Transcript membranes notes (powerpoint)

Planes and Positions,
Body Cavities and
Membranes
PLANES
3 major planes:
Median Sagittal Plane- a sagittal
cut that runs directly through the
median.

POSITIONS
The Basic Regions
dorsal: toward the back of the body
 ventral: toward the underside of the
body
 anterior (cranial): toward the head end
of the body
 posterior (caudal): toward the tail end
of the body

lateral: to the side of the body
 median: toward the center of the body
 right and left: the pig's right and left,
not yours!
 proximal or basal: closer to the trunk
 distal: farther from the trunk

Body Regions
cranial region: head
 cervical region: neck
 thoracic region: trunk
 caudal region: abdomoninal region/tail
region
 pelvic region: near pelvis
 Pectoral region: shoulder area

Thoracic Cavity- above the
diaphragm
Pleural Cavity- contains lungs
Pericardial Cavity- contains
heart
Pericardial Cavity
Abdominal Cavity (Peritoneum)
 Cavity
below the diaphragm
MEMBRANES
Membranes- what is the function
of the following?
Parietal Pleura
 Visceral Pleura
 Parietal Peritoneum
 Visceral Peritoneum
 Pericardium
 Greater Omentum
 Mesentery

Break it down…
Parietals – Line the CAVITY they are in
 Viscerals – Line the ORGANS

Pleura – refers to the chest area (pleural cavity)
 Peritoneum – refers to the abdominal area

Pericardial – peri = around; cardial= the heart
 Greater Omentum- holds the spleen in place by
attaching it to the stomach
 Mesentery- between the parts of the small
intestine

So let’s try this again…
Parietal Pleura
 Visceral Pleura
 Parietal Peritoneum
 Visceral Peritoneum
 Pericardium
 Greater Omentum
 Mesentery

Other membrane types

Synovial Membranes 

Serous Membranes


These membranes secrete a watery fluid to keep the organs in
the cavities lubricated and separated so they are able to move.
Meninges


These membranes secrete a fluid to lubricate the ends of bones
in joints.
These membranes provide a protective covering for the brain
and spinal cord.
Mucous Membranes

These membranes line the tubes of the digestive system,
respiratory system, urinary system, and reproductive system for
protection.
