TISSUE TEST CRAM

Simple squamous epithelium

• What it does: Reduces friction; controls vessel permeability; performs absorption and secretion

• Found in: Epithelia lining ventral body cavities; lining heart and blood vessels; portions of kidney tubules (thin sections of nephron loops); inner lining of cornea; alveoli (air sacs) of lungs

Simple cuboidal epithelium

• What it does: Limited protection, secretion, absorption

• Found in: Glands; ducts; portions of kidney tubules; thyroid gland

Simple columnar epithelium

• What it does: Protection, secretion, absorption

• Found in: Lining of stomach, intestine, gallbladder, uterine tubes, and collecting ducts of kidneys

Stratified squamous epithelium

• What it does: Provides physical protection against abrasion, pathogens, and chemical attack

• Found in: Surface of skin; lining of mouth, throat, esophagus, r-ctum, an-s, and v-gina

Pseudostratified ciliated columnar epithelium

• What it does: Protection, secretion, move mucus with cilia

• Found in: Lining of nasal cavity, trachea, and bronchi; portions of male reproductive tract

Transitional epithelium

• What it does: Permits expansion and recoil after stretching

• Found in: Urinary bladder; renal pelvis; ureters

Aereolar

• FUNCTIONS: Cushions organs; provides support but permits independent movement; phagocytic cells provide defense against pathogens

• WHERE: Beneath dermis of skin, digestive tract, respiratory and urinary tracts; between muscles; around blood vessels, nerves, and around joints

Adipose

• FUNCTIONS: Provides padding and cushions shocks; insulates (reduces heat loss); stores energy

• WHERE: Deep to the skin, especially at sides, buttocks, breasts; padding around eyes and kidneys

Reticular

• FUNCTIONS: Provides supporting framework

• WHERE: Liver, kidney, spleen, lymph nodes, and bone marrow

Dense Regular

• FUNCTIONS: Provides firm attachment; conducts pull of muscles; reduces friction between muscles; stabilizes relative positions of bones

• WHERE: Between skeletal muscles and skeleton (tendons and aponeuroses); between bones or stabilizing positions of internal organs (ligaments); covering skeletal muscles deep fasciae

Dense Irregular

• FUNCTIONS: Provides strength to resist forces applied from many directions; helps prevent overexpansion of organs such as the urinary bladder

• WHERE: Capsules of visceral organs; periostea and perichondria; nerve and muscle sheaths; deep dermis of the skin

Blood

• FUNCTIONS: Carry specific cell types (formed elements)

• WHERE: Cardiovascular System

Lymph

• FUNCTIONS: Carry specific cell types (formed elements)

• WHERE: Lymphatic system

Bone

• FUNCTIONS: For weight support

• WHERE: Vertebrate skeletal structures

Elastic Cartilage

• FUNCTIONS: Supportive but bends easily

• WHERE: External ear and epiglottis

Hyaline Cartilage

• FUNCTIONS: Reduces friction between bones

• WHERE: Synovial joints, rib tips, sternum, and trachea

Fibrocartilage

• FUNCTIONS: Limits movement, Prevents bone-to-bone contact, Pads knee joints

• WHERE: Pubic bones and intervertebral discs
