3 basic components of connective tissue

1. specialized cells 2. extracellular protein fibers 3. ground substance

Exocrine glands

Glands that release secretions outward through a duct

Which type of connective tissue is found between the ribs and the sternum, or supporting the trachea?

Hyaline Cartilage

A type of intercellular junction that stops materials from crossing an epithelium between cells is termed a(n)

Tight Junction

Merocrine secretion

product is released from secretory vesicles by exocytosis

Mucin

protein element of mucus

Holocrine secretion

release of a substance caused by the rupture of a gland cell packed with secretory products, which becomes part of the secretion and kills cell

Endocrine Glands

release their secretions directly into the blood, interstitial fluid

Nonkertinized Stratified Squamous Epithelium

resists abrasion but will dry out and deteriorate

Goblet cells

secrete mucin that hydrates to form mucus, these cells are scattered among absorptive cells in the epithelial of intestines

Stratified Squamous Epithelium is generally located where physical and chemical stresses are severe. These cells are found...

surface of the skin/line of mouth, throat, esophogus, rectum, anus, and vagina

The dominant fiber type in most dense connective tissue is

collagen

Interstitial fluid

fluid between cells

During an inflammatory response to injury, which of the following is least likely in the region of the injury?

pale, cold skin

The simple squamous epithelium lining the inner surface of the heart and blood vessels is called?

An endothelium

What lines the pericardial, pleural, and peritoneal cavities?

A mesothelium
