What is a corticosteroid and calcitrol? Metabolic regulators
What happens in the G2 Phase? Finishing of protein synthesis and centriole replication
What is the function of smooth ER? Synthesize lipids and carbohydrates
What are globular proteins? Soluble spheres with active functions
What happens in the S Phase? DNA replication and histone synthesis
Characteristics of Reticular fibers Resists force in many directions (sheaths around organs)
What are the 6 functions of membrane proteins? Anchoring, recognition, enzymes, receptor, carrier, channels
What is a Triglyceride? Fat storage molecule
What does mesothelium line? Body cavities
What are the 3 components of the cell membrane? Lipids, carbohydrates, proteins
What are peroxisomes? Enzyme-containing vesicles that break down fatty acids and organic compounds and produce H2O2
What does endothelium line? Heart and blood vessels
What are Prostaglandins? Short-chain fatty acids, local hormones
Characteristics of collagen fibers Most common in connective tissue proper, resists force in 1 direction (tendons and ligaments)
What is radiant energy? Electromagnetic (energy in waves)
What are the 5 types of lipids? Fatty acids, eicosanoids, glycerides, steroids, phospholipids, and glycolipids
What happens in the G1 phase? Cell growth, organelle duplication, protein synthesis
What is the function of ER? Synthesis of protein, storage of synthesized molecules, and detoxification of drugs and toxins
What are fibrous proteins? Structural sheets or strands
What are the 2 types of Eicosanoids? Leukotrienes and prostaglandins
What is Merocrine secretion? Produced by Golgi body released by vesicles (sweat glands)
What are the 3 membrane carbohydrates? Proteoglycans, glycoproteins, and glycolipids
What are the 4 types of steroids? Cholesterol, estrogen and testosterone, corticosteroid and calitrol, and bile salts
What are the characteristics of epithelial tissue? Cellularity, polarity, attachment, avascularity, and regeneration
What are the functions of epithelial tissue? Provide physical protection, control permeability, provide sensation, and produce specialized secretions
What is the function of simple squamous epithelium? Absorption and diffusion
What is the function of stratified squamous epithelium? Protects against attacks
What is the function of simple cuboidal epithelium? Secretion and absorption (kidney tubules)
What is the function of stratified cuboidal epithelium? Sweat and mammary ducts
What is the function of simple columnar epithelium? Absorption and secretion
What is the function of stratified columnar epithelium? Protection
What are the types and functions of glandular epithelium? Endocrine glands that release hormones into interstitial fluid and have no ducts and exocrine glands that produce secretions onto epithelial surfaces through ducts
What is dense regular connective tissue for? Attachment and stabilization (tendons, ligaments)
What is dense irregular connective tissue for? Layered in skin, around cartilage, around bones, and form capsules around some organs (liver, kidneys)
Characteristics of fibrocartilage Limits movement, prevents bone to bone contact, pads knee joints, found between pubic bones and intervertebral discs
Characteristics of Hyaline cartilage Stiff, flexible support, reduces friction between bones, found in synovial joints, rib tips, sternum, and trachea
Where is areolar tissue found? Holds blood vessels and capillary beds (under skin)
Where is reticular tissue found? Supportive fibers that support functional cells, reticular organs, spleen, liver, lymph nodes, and bone marrow
