Tissues Flashcards
Adipose Tissue
“Closely packed fat cells, have nucleus pushed to the side”
Location: under skin, around kidneys and eyeballs
Function: Provides reserve food feul, protects organs
Areolar tissue
“Gel-like matrix with all three fiber types”
Location: Under epithelia, surrounds capillaries
Function: wraps and cushions organs, phagocytes engulf bacteria
Reticular Connective Tissue
“Network of reticular fibers in a typical loose ground substance”
Location: Lymphoid organs (lymph nodes, bone marrow and spleen)
Function:Form a soft internal skeleton that supports other cell types
Hyaline Cartilage
“Firm matrix”
Location: Forms most of embryonic skeleton, covers the end of long bones in joint cavities
Function: Supports and reinforces, has cushioning properties, resists compression
Bone (Osseous) Tissue
“Hard, calcified matrix”
Location: Bones
Function: Supports and protects
Stratified Squamous Epithelium
Protects against abrasion and friction
Keratinized: Dead and found in epidermis
Nonkeratinized: Alive and found in esophagus and oral cavity
Red Blood Cells
Deliver oxygen; found in blood
Fibrocartilage
Stongest type of cartilage
Found in intervertebral disk
Cardiac Muscle
Found in the heart
Some striations
Smooth Muscle Tissie
No striations
Found in digestive tract
Simple Squamous Epithelium
Allows rapid movement of molecules surface
Found in air sacs of lungs, lining blood and lymph vessel walls
Elastic Cartilage
Provides strength and elasticity
Found in external ears
Skeletal Muscle
Used for movement
Found alongside bones
Simple Cuboidal Epithelium
Absorbs fluids across apical surface & Secretes materials
Forms secretory regions of most glands
Simple Columnar Epithelium
Ciliated: Moves mucus along, present in bronchioles and Uterine tubes
Nonciliated: increases surface area, lines digestive tract
Neurons
Detect changes in body and respond by generating impulses
Dense Regular Connective Tissue
Found in tendons and most ligaments
Dense Irregular Connective Tissue
Pulled in different directions
Found in the dermis
PSeudostratified Columar Epithelium
Ciliated: moves mucus, found in large passageways of respiratory system
Nonciliated: Occurs mainly in male urethra and epididymis
Transitional epithelium
Limited to the urinary tract
Allows for stretching, contains binucleated cells
