Question 22

Function and Location:

Areolar Connective

Answer 22

Serves as soft packing around organs capable of inflation in case of injury: found in outer layers of skin and muscle, mucus membranes and organs

Question 23

Function and Location:

Adipose Connectice

Answer 23

Insulation, storage of nutrients and energy; found in breasts, abdomen, subcutaneous tissue, around heart, kidneys and joints

Question 24

Function and Location:

Reticular Connective

Answer 24

Delicate scaffolding that supports reticular and free blood cells; found around kidney, spleen, lymph nodes and in bone marrow

Question 25

Function and Location:

Regular Dense

Answer 25

Retains great tensile stress, holding together bone and muscle to passively assist with movement; found in tendons and ligaments

Question 26

Function and Location:

Irregular Dense

Answer 26

Withstands tensile strength, passively allowing for movement of the tubular organs, dermis of skin and glandular tissues it makes up

Question 27

Function and Location:

Elastic Dense

Answer 27

Flexible tissue allows for stretch and contraction of organs without harm; found in lungs, trachea, bronchial tubes and thyroid ligaments

Function and Location:

Elastic Cartilage

Answer 29

Provides flexibility for specialized function; found in pinna of ear and epiglottis

Question 30

Function and Location:

Fibrocartilage

Answer 30

Cartilage most like dense connective, structured to withstand significant tensile stress with some limited movement with added flexibility; found esp. in intervertebral discs of shoulder blades
