Anatomy Chapter 4
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
