Chapter 5: Tissues Flashcards
What are the 4 major types of tissues?
Epithelial tissue
Connective tissue
Muscle tissue
Nervous tissue
What are the types of glandular secretion? And their functions?
Merocrine glands: a fluid product released through the cell membrane by exocytosis
Apocrine glands: lose small parts of cell during secretion
Holocrine glands: release entire cells filled with product
What are the structural types of exocrine glands?
Simple:
Compound:
Tubular:
Alveolar:
What are fibroblasts?
Large star shaped cell
What are the types of intercellular junctions?
Tight junctions, Desmosomes, Gap junctions
What are the characteristics of tight junctions?
close space between cells by fusing cell membranes; blood-brain barrier
What are the characteristics of Desmosomes?
Bind cells by forming “spot welds” b/w cell membranes; Located among outer skin cells
What are the characteristics of Gap junctions?
form tubular channels b/w cells that allow exchange of substances; located in cardiac muscle cells
What type of gland are salivary and sweat glands?
Merocrine
What type of gland are mammary and ceremonious glands?
Apocrine
What type of gland are sebaceous glands?
Holocrine
What are the 2 types of glands? and what do they do?
Endocrine: secrete into tissue fluid or blood
Exocrine: Secrete into ducts that open onto surface
Where is nervous tissue found? What is its function?
Found in brain, spinal cord, and peripheral nerves.
Sensory reception, release of neurotransmitters, and conduction of electrical impulses.
What are the 3 types of epithelial membranes?
Serous membranes
mucous membranes
cutaneous membranes
How is synovial membranes different from epithelial membranes?
Composed entirely from connective tissue; lines joint cavities
What is cutaneous membranes?
Covers body surface; commonly called skin
Where is serous membranes located?
lines body cavities that do not open outside of the body; inner linings of thorax and abdomen, covers organs
Which membrane is made out of simple squamous epithelium and areolar connective tissue?
Serous Membranes
Which membrane is made out of epithelium and areolar connective tissue?
Mucous membranes
Where is mucous membranes?
lines cavities and tubes that open outside of the body; lining of digestive, respiratory, urinary, and reproductive tracts
What are the 4 structural types of exocrine glands?
Simple
compound
tubular
alveolar
What is the function of skeletal muscle tissue and its location?
Voluntary movements of skeletal parts.
Muscles usually attached to bones
What is the function of cardiac muscle tissue and its location?
Heart movements
found in the heart muscle
What is the function of smooth muscle tissue and its location?
Involuntary moments of internal organs.
walls of hollow internal organs
