Q

Body wall

A

consists of structures forming the body’s framework, supporting and enclosing vital organs.

Comprised of the skin, skeleton, and muscle.

The head, arms, and legs are considered as specialized extensions of the body wall.

Q

What are the 4 functions of body cavities?

A

1) house and seperate organs

2) protect and cushion organs from external impact

3) allow considerable freedom for movement of internal organs without disrupting function of other organs

4) enable different pressures to be created within body without disrupting other organs

96
Q

What are the 2 principal body cavities?

A

1) Dorsal body cavity
2) Ventral body cavity (Coelom)

97
Q

Dorsal body cavity

A

cushions and protects the CNS (brain and spinal cord)

a. cranial cavity- formed by bones of skull; houses brain

b. spinal (vertebral) cavity- formed by verterbral column; houses spinal cord

98
Q

Ventral body cavity (coelom)

A

enclosed by ribs and abdominal and lumbar musculature.

Surrounds organs of respiratory, digestive, cardiovascular, urinary, and reproductive systems.

a. thoracic cavity: enclosed by ribcage and seperated from abdominopelvic cavity by the diaphram.
1. right & left pleural cavities: house the 2 lungs
2. pericardial cavity: houses heart

b. abdominopelvic cavity: enclosed by abdominal and lumbar muscles. inferor to diaphram. houses abdominal viscera (organs).
1. Abdominal cavity: separated from inferior pelvic cavity by an imaginary line at the pelvic brim; houses digestive organs and glands
2. pelvic cavity: separated from inferior abdominopelvic cavity by imaginary line at the pelvic brim. houses urinary and reproductive systems, distal portions of the digestive systems

99
Q

Serous membranes

A

line and enclose several body cavities & organs where they secrete a lubricating fluid to reduce friction from muscle movements

100
Q

What is the difference between visceral and parietal serous membranes?

A

Visceral: cover body organs

Parietal: cover and line body cavities

101
Q

102
Q

types of parietal serous membranes

A

[cover and line body cavities]

a. Parietal pleura: membrane lining pleural cavity

b. Parietal pericardium: membrane lining pericardial cavity

c. Parietal peritoneum: membrane lining the abdominopelvic cavity

103
Q
