Study Notes

Mesenchyme

Forms almost all types of connective tissue.
Primarily located under the skin and along developing bones of embryos; some found in adult tissue along blood vessels.

Mucous Connective Tissue

Functions to provide support.
Located in the umbilical cord of the fetus.

Areolar Connective Tissue

Provides strength, elasticity, and support.
Found in nearly every body structure, including the subcutaneous layer beneath the skin, papillary region of the dermis, lamina propria of mucous membranes, and surrounding blood vessels, nerves, and organs.

Adipose Tissue

Reduces heat loss through skin, serves as an energy reserve, and supports/protects organs. In newborns, brown adipose tissue generates heat for body temperature maintenance.
Located in subcutaneous layers, around the heart and kidneys, yellow bone marrow, and as padding around joints and behind the eyeballs.

Reticular Connective Tissue

Forms the stroma of organs, binds smooth muscle tissue cells, filters out worn-out blood cells in the spleen and microbes in lymph nodes.
Located in the liver, spleen, lymph nodes, red bone marrow, and around blood vessels and muscles.

Dense Regular Connective Tissue

Provides strong attachment between structures and withstands pulling tension along the axis of the fibers.
Found in tendons (attaching muscle to bone), most ligaments (attaching bone to bone), and aponeuroses (sheet-like tendons connecting muscle to muscle or bone).

Dense Irregular Connective Tissue

Offers tensile strength in multiple directions.
Commonly found in sheets, such as fasciae, the deeper region of the dermis, fibrous pericardium of the heart, periosteum of bone, perichondrium of cartilage, joint capsules, and membranes around organs.

Elastic Connective Tissue

Allows for stretching and recoiling of organs; essential for lung function during exhalation and maintaining blood flow in elastic arteries.
Located in lung tissue, walls of elastic arteries, trachea, bronchial tubes, true vocal cords, and some ligaments between vertebrae.

Hyaline Cartilage

Provides smooth joint surfaces, flexibility, and support; considered the weakest type of cartilage and can fracture.
Most abundant cartilage in the body, found at the ends of long bones, anterior ends of ribs, nose, larynx, trachea, bronchi, bronchial tubes, and embryonic skeletons.

Fibrocartilage

Supports and connects structures; strongest type of cartilage due to its strength and rigidity.
Located in the pubic symphysis, intervertebral discs, menisci of the knee, and areas where tendons insert into cartilage.

Elastic Cartilage

Provides strength and elasticity, maintaining the shape of certain structures.
Located in the epiglottis, external ear (auricle), and auditory (eustachian) tubes.

Bone Tissue

Functions for support, protection, and storage, and houses blood-forming elements.
