Tissues Flashcards
(20 cards)
Types of tissues
Epithelial, connective, muscle, nerve
Epithelial tissue
continuous sheets that serve as lining
Connective tissue
adds support and structure to the body
Muscle tissue
Can contract
Nerve tissue
has ability to generate and conduct electrical signals
Functions of Epithelial
Protecting, barrier, permitting passage, secreting substances
Simple layered epithelia
Squamous, cuboidal, columnar
Pseudostraitified
Columnar
Stratified
squamous (moist, keratinized)
Sensory cell tissue structure
Columnar
Connections of epithelial cells
Tight junctions, desmosomes, hemidesmosomes, gap junctions
Connective tissues subdivision
Loose, Dense, Specialized (Tendons, ligaments)
Cartilage
Connective tissue, found in ear
Bone composition
Osteoblasts, osteocytes, collagenous fibers and ground substance
Osteoblasts
Generate/form new bone through life
Marrow
Produces new red blood cells (maintenance)
Three types of muscle tissue
Striated, smooth muscle, and cardiac muscle
Striated muscle function
Voluntarily controlled, skeletal, stapedius muscle
Smooth muscle function
Involuntary muscle, ANS, found in stomach and intestines
Nerve tissue
responsible for coordinating and controlling body
