Areolar Connective Tissue
In and around every body structure: in subcutaneous layer deep to skin; papillary (superficial) region of dermis of skin; lamina propria of mucus membranes; around blood vessels, nerve and body organs.
Reticular Connective Tissue
Stroma (supporting framework) of liver, spleen, lymph nodes; red bone marrow; reticular lamina of basement membrane; around blood vessels and muscles.
Dense Regular Connective Tissue
Forms tendons (attach muscle to bone), most ligaments (attach bone to bone) and aponeuroses (sheetlike tendons that attach muscle to muscle or muscle to bone).
Dense Irregular Connective Tissue
Often occurs in sheets such as fasciae (tissue beneath the skin and around muscles and other organs), reticular (deeper) region of dermis of skin, fibrous pericardium of cartilage, joint capsules, membrane capsules around various organs (kidneys, liver, testes, lymph nodes); also in heart valves.
Elastic Connective Tissue
Lung tissue, walls of elastic arteries, trachea, bronchial tubes, true vocal cords, suspensory ligaments of penis, some ligaments between vertebrae.
Most abundant cartilage in body; at ends of long bones, anterior ends of ribs, nose, part of larynx, trachea, bronchi, bronchial tubes, embryonic and fetal skeleton.
Lid of top of larynx (epiglottis), part of external ear (auricle), auditory (eustachian) tubes.
Pubic symphysis (where hip bones join anteriorly), intervertebral discs, menisci (cartilage pads) of knee, portions of tendons that insert into cartilage.
