loose network of wispy mesenchymal cells embedded in gelatinous ground substance.

Question 2

messenchyme connective tissue- location

Answer 2

fetal connective tissue

Question 3

messenchyme connective tissue- function

Answer 3

gives rise to cardiac, and smooth muscle, cartilage, bone, and blood.

Question 4

Areolar CT

Answer 4

loose arrangement of collagenous and elastic fibers, scattered cells of various types abundant ground substance numerous blood vessels

Question 5

Areolar CT- location

Answer 5

underlying nearly all epithelia surrounding blood vessels, nerves, esophagus and trachea. fasciae between muscles, messenteries, visceral layers of pericardium and pleura

Question 6

Areolar CT- function

Answer 6

loosely binds epithelia to deeper tissues, allows passage of nerves and blood vessels through other tissues provides an arena for immune defense provides nutrients and waste removal for overlying epithelia

Question 7

Adipose CT

Answer 7

dominated by adipocytes large empty looking cells

Question 8

Adipose CT- location

Answer 8

fat beneath skin, breast, heart surface, mesenteries, surround kidney and eye

Question 9

Adipose CT- function

Answer 9

energy storage thermal insulation, protective cushion, filling space and shaping body

Question 10

Reticular CT

Answer 10

loose network of reticular fibers and cells, infiltrated with numerous lymphocytes and other blood cells

Question 11

Reticular CT- location

Answer 11

lymph nodes, spleen, thymus, bone marrow

Question 12

Reticular CT- function

Answer 12

supportive stroma (framework) for lymphatic organs

Question 13

Dense regular white fibrous CT

Answer 13

densely packed, parallel, often wavy collagen fibers, slender fibroblast nuclei compressed between collagen bundles, scanty open space (ground substance) scarcity of blood vessels

Question 14

Dense regular white fibrous CT- location

Answer 14

tendons and ligaments

Question 15

Dense regular white fibrous CT- function

Answer 15

ligaments tightly bind bones together and resist stress, tendons attach muscle to bone and move the bones when the muscles contract

Question 16

Dense Irregular white fibrous CT

Answer 16

densely packed collagen fibers running in random directions, scanty open space (ground substance) few visible cells, long fibers in the tissue appear as short, chopped up pieces in thin histological sections

Question 17

Dense Irregular white fibrous CT- location

Answer 17

deeper portion of dermis of skin, capsules around viscera such as liver, kidney, spleen, fibrous sheaths around muscles, nerves cartilages, and bones

Question 18

Dense Irregular white fibrous CT- function

Answer 18

durable hard to tear, variable orientation of fibers withstands stresses applied in unpredictable directions

Question 19

Elastic Connective Tissue

Answer 19

modified dense connective tissue contains numerous elastic fibers, collagen fibers

Question 20

Elastic Connective Tissue- location

Answer 20

where tendons attach to bones, the intervertebral discs and pubic symphysis

Question 21

Elastic Connective Tissue- function

Answer 21

help connective tissue to stretch and recoil
