Lab 3: CT Projections

Question 1

Answer 1

Adipose Tissue

Characteristics: Adipocytes with compressed, laterally displaced nucleus; blood capillaries visible; white adipose is unilocular and brown adipose is multiocular

Function: Storage and metabolism of fat; cushioing of vital organs; insulation

Location: White adipose: subcutaneous tissues, omenta, mensenteries, pararenal tissue, and bone marrow; Brown adipose: newborns and interscapular and inguinal regions

Question 2

Answer 2

Areolar Connective Tissue

Characteristics: Loosely arranged with numerous collagen fibers, few elastic fibers, fibroblasts, macrophages, and other cellular components

Function: Forms fascia that binds organs and organ components together

Location: Most organs and tissues; expandale tubular structures such as ducts and glands

Question 3

Answer 3

Dense Irregular CT

Characteristics: Think, intertwined bundles of collagen fibers arranged haphazardly with fibroblasts and microphages present

Function: Cushioning; Provides attachment for ligaments

Location: Dermis, capsules of organs, periosteum, perichondrium

Question 4

Answer 4

Dense Regular CT

Characteristics: Collagen bundles arranced in bundles with a regular, precise arrangement; fibers oriented in direction of pull

Function: Joins bone together; muscles as well

Location: Collagenous dense regular CT is found in tendons, ligaments, aponeurosis, and cornea; elastic is found in ligamentum nuchae and ligamentum flava

Question 5

Answer 5

Elastic Tissue

Characteristics: Concentric sheels of elastic fibers (elastic laminae) with wave-like appearance

Function: Elasticity and recoiling action of aorta and large arteries

Location: Aorta and large arteries
