Chapter 4 Part 1 Flashcards
______ are groups of cells similar in structure and function.
Tissues
What are the four types of tissues?
1.) Connective
2.) Muscle
3.) Epithelial
4.) Nerve
(CMEN)
What type of tissue has polarity (apical and basal surfaces), has special contacts, is composed almost entirely of cells, and is avascular but innervated?
epithelial tissue
Epithelial tissue is “avascular but innervated.” What does this mean?
it means that epithelial tissue contains no blood vessels, but is supplied by nerve fibers.
_______ epithelium are present in kidney tubules, ducts and secretory portions of small glands, and ovary surfaces.
Simple cuboidal
_______ epithelia streets to permit the distension of the urinary bladder.
Transitional
______ are ductless glands that produce hormones and secrete amino acids, proteins, glycoproteins, and steroids.
Endocrine glands
______ products are secreted by exocytosis (e.g., pancreas, sweat, and salivary glands).
Merocrine
______ products are secreted by the rupture of gland cells (e.g., sebaceous glands).
Holocrine
What are the four types of connective tissue?
- ) Connective tissue proper
- ) Cartilage
- ) Bone
- ) Blood
The functions of _______ are binding and support, protection, insulation, and transportation.
connective tissue
What are the structural elements of connective tissue?
- ) ground substance
- ) fibers
- ) cells
Name and describe the three types of fibers present in connective tissue.
- ) Collagen - tough, provides high tensile strength.
- ) Elastic - long, thin fibers that allow for stretch.
- ) Reticular - branched collagenous fibers that form delicate networks.
______ are the stem cells for the blood.
Hematopoietic stem cells
______ are the stem cells for bone.
Osteoblasts
