Included in what cavity?

Answer 11

Cranial Cavity

Dorsal Cavity

Question 12

The space inside the spinal column containing the spinal cord

Included in what cavity

Answer 12

Spinal Cavity (Vertebral Canal)

Dorsal Cavity

Question 13

The space containing the heart, lungs, esophagus, trachea, bronchi, and thymus

Included in what cavity?

Answer 13

Abdominal Cavity

Ventral Cavity

Question 15

The space containing the urinary bladder, certain reproductive organs, part of the large intestine, and the rectum

Included in what cavity?

Answer 15

Pelvic Cavity

Ventral Cavity

Question 16

These line the interior walls of the organs and tubes opening to the outside of the body. Lined w/ epithelium overlaying a layer of connective tissue called lamina propria.

Answer 16

Mucous Membranes

Question 17

These line cavities, including the thoracic cavity and internal organs. Consist of a layer of simple squamous epithelium overlaying a layer of loose connective tissue. Support internal organs to hinder spread of infection.

Answer 17

Serous Membranes

Question 18

These line joint cavities and are composed of connective tissue. They secrete fluid into the joint cavity; this lubricates the ends of bones to move freely

Answer 18

Synovial Membranes

Question 19

Composed of three connective tissue membranes found within the dorsal cavity and serve as a protective covering of the brain and spinal cord. Outer layer to inside payer are dura mater, arachnoid mater, and pia mater

Answer 19

Meninges

Question 20

This membrane forms the outer covering of the body and consists of a thin layer of stratified squamous epithelium attached to a thicker underlying layer of connective tissue. It is skin

Answer 20

Cutaneous Membrane
