Locations of Loose Reticular CT

Answer 20

Lymphoid organs (ex. Spleen, 
bone marrow, lymph nodes)

Question 21

Types of Dense CT

Answer 21

Dense Regular, Dense Irregular, Dense Elastic

Question 22

Function & Locations of Dense Regular CT

Answer 22

provide strength in one direction

Tendons & Ligaments

Question 23

Characteristics & Function of Dense Irregular CT

Answer 23

Collagen fibers run in many different directions to each other
Able to resist strong tensions from different directions

Question 24

Location of Dense Irregular CT
