- 1What are the 4 main tissue types?Epithelial, Connective, Muscular and Nervous
- 2Give a basic description of the 4 major tissue typeEpithelial: covers body surface, lines hollow organs, forms glands.
Connective: protect/support the body and its organs.
Muscular: moves/generates heat
Nervous: communicates - 3List the 4 different types of Connective TissueFibrous (loose and dense), Bone, Blood and Cartilage
- 4List 3 locations of Muscle TissueSkeletal - attached to the skeleton
Cardiac - heart wall
Smooth - walls of hollow organs - 5What are the 2 types of Epithelial Tissues?1. Covering and lining epithelium
2. Glandular epithelium - 6What are the classifications of layers of epithelial tissue? Describe their appearance and function.Simple = only one layer, functions in diffusion, secretion and absorption
Pseudostratified = one layer but looks like multiple
Stratified = two or more layers, functions in preventing wear and tear - 7Name and explain the types of Epithelial Tissue Cell shapes. what are there functions?Squamous = flattened shape, allow easy passage of materials right across the layer
Columnar = Column shape, secretion and absorption
Cuboidal = Cube shape, secretion and absorption - 8What is the function and location of a Simple Squamous Epithelium?Function: allows passage of material by diffusion and filtration, secretion in serous membranes
Location: lining of heart, blood and lymphatic vessels, serous membranes, air sacs of lungs, glomerular capsule of kidneys - 9What is the function and location of a Simple Cuboidal Epithelium?Function: Secretion and absorption
Location: lines kidney tubules, covers ovary surface, makes up secreting portion of glands - 10What is the difference between ciliated and non ciliated Epithelium?ciliated means it has cilia on its surface. non ciliated do not have cilia present.
- 11What is the function and location of a Simple Columnar Epithelium (non-ciliated)?Function: high levels of secretion and absorption, lubricates linings of digestive, respiratory and reproductive tracts
Location: line GI tract, ducts of some glands and the gall bladder - 12What is the function and location of a Simple Columnar Epithelium (ciliated)?Function: cilia beat in motion, moving mucus and foreign particles towards the throat, moving oocytes from ovaries into the uterus
Location: lines bronchioles of respiratory tract, uterine tubes, central canal of spinal cord and ventricles of brain - 13What is the function and location of a Pseudostratified ciliated columnar epithelium?Function: secretes mucus that trap foreign particles and sweep away mucous for elimination
Location: lines airways of most of the upper respiratory tract - 14What is the difference between keratinised and non-keratinised Epithelial?Keratinised epithelial means it has developed a tough layer of keratin in apical layer of cells and several layers deep to it
- 15What is Keratin?A tough, fibrous intracellular protein that helps protect skin and underlying tissues from heat, microbes and chemicals
- 16What is the function and location of a Stratified Squamous Epithelium (Keratinised)?Function: protects against abrasion, water loss, ultraviolet radiation and foreign invasion
Location: form superficial layer of skin - epidermis - 17What is the function and location of a Stratified Squamous Epithelium (Non-keratinised)?Function: protects against abrasion and foreign invasion
Location: lines wet surfaces - mouth, oesophagus, epiglottis, vagina, cover tongue - 18What is the function and location of a Transitional Epithelium?Function: allows urinary organs to stretch and maintain protective lining while holding variable amounts of fluid without rupturing
Location: Line urinary bladder and portions of ureters and urethra - 19Describe Transitional Epitheliumhas a variable appearance, in relaxed/unstretched state - looks like stratified cuboidal epithelium, as the tissue stretches cells flatten giving the appearance of stratified squamous epithelium.
- 20Define the Apical layerThe Apical layer of cells is how stratified epithelium is named, it is the layer closest to the free space (surface)
- 21What are the 2 types of Glandular Epithelium? What are their main differences?Exocrine and Endocrine. Exocrine secrete via a duct onto a surface, Endocrine secretes into the blood stream.
- 22Give the description, function and location of Exocrine Glandular EpitheliumExocrine uses ducts to empty on the skins surface or into lumen of hollow organs. Function is to produce substances (sweat, oil, saliva, digestive enzymes).
Located in sweat, oil and salivary glands and the pancreas. - 23Give the description, function and location of Endocrine Glandular Epitheliumsecrete hormones which are transported into blood, hormones regulate metabolic and physiological activities to maintain homeostasis. Located in the pituitary, thyroid and parathyroid glands and the pancreas
- 24What is the most common tissue in the body?Connective tissue
- 25List some functions of Connective Tissue- binds together and supports other tissues
- protects and insulates organs
- compartmentalizes structures
- is the body's major transport system - 26What is connective tissue made of?Ground substance, Cells and Fibres
- 27What is Ground substance?- the material that supports the cells and fibres
- plays active roles in how tissues develop, migrate and proliferate
- can be liquid (blood), a gel (loose under skin) or very hard (bone) - 28What are the 3 types of protein fibres in connective tissue?Collagen, elastin and reticular fibres
- 29what do collagen fibres provide?toughness and strength
- 30what do elastin fibres provide?stretch and recoil (elasticity)
- 31what do reticular fibres provide?support and attachment
- 32Where are the following cells found? Osteocytes, Chondrocytes, Erythrocytes and leucocytes, Adipocytes, fibroblastsOsteocytes - Bone
Chondrocytes - Cartilage
Erythrocytes & Leucocytes - Blood
Adipocytes - Fat tissue
Fibroblasts - produce fibres - 33What is the function
