Microscopic Anatomy - Tissues Flashcards
What are four major types of tissues?
- Epithelial
- Connective
- Muscle
- Nervous
What are five characteristics of epithelial tissues?
- Cover organs and the body.
- Line body cavities.
- Line hollow organs.
- Have a free surface.
- Have a basement membrane.
- Avascular
- Cells readily divide.
- Cells tightly packed.
- Cells often have desmosomes.
- Function in protection, secretion, absorption, and excretion.
- Classified according to cell shape and number of cell layers.
What are four functions of epithelial tissues?
- Secretion
- Excretion
- Absorption
- Protection
Where would you find Simple Squamos epithelial tissues?
- Line air sacs.
- Line blood vessels.
- Line lymphatic vessels.
Where would you find Simple Cuboidal epithelial tissues?
- Line kidney tubules.
- Cover ovaries.
- Line ducts of some glands.
Where would you find Simple Columnar epithelial tissues?
Line the uterus, stomach, and intestines.
Where would you find Pseudostratified Columnar epithelial tissues?
Line respiratory passageways.
Where would you find Stratified Squamos epithelial tissues?
Line oral cavity, throat, vagina, and anal cavity.
Where would you find Stratified Cuboidal epithelial tissues?
Line ducts of mammary glands, sweat glands, salivary glands, and the pancreas.
Where would you find Stratified Columnar epithelial tissues?
Line vas deferens, male urethra, and part of pharynx.
What are three major cell types of connective tissues?
- Fibroblasts
- Macrophages
- Mast Cells
What are three connective tissue fibers?
- Collagenous
- Elastic
- Reticular
Where would you find nervous tissues in the body?
Nervous tissues are found in the brain, spinal cord, and the peripheral nerves.
Name three disorders that are associated with collagen defects.
- Chondrodysplasia
- Dystrophic Epidermolysis Bullosa
- Hereditary Osteoarthritis
Give an example of merocrine glands.
Salivary glands, sweat glands, pancreas
Give an example of apocrine glands.
Mammary glands, ceruminous glands
Give an example of holocrine glands.
Sebaceous glands
What are three specialized connective tissues?
- Cartilage
- Bone
- Blood
Where would you find loose connective tissues?
Between muscles.
Where would you find adipose tissues?
Around kidneys and heart.
Where would you find reticular connective tissues?
Walls of liver, spleen, and lymphatic organs.
Where would you find dense connective tissues?
Tendons, ligaments, dermis.
Where would you find elastic connective tissues?
Walls of large arteries, airways, and heart.
Where would you find bone tissues?
Attached to the skeleton.
Where would you find cartilage?
Between the bones, in the joints, ears, nose, vertebrae, and bronchial tubes.
What are three types of cartilage?
- Hyaline cartilage
- Elastic cartilage
- Fibrocartilage
Where would you find Hyaline cartilage?
Ends of bones, nose, respiratory passages, and embryonic skeleton
Where would you find Elastic cartilage?
External ear and larynx
Where would you find Fibrocartilage?
Invertebral discs, pads of knee, and pelvic girdle
What are three muscle tissues?
- Skeletal Muscle
- Smooth Muscle
- Cardiac Muscle
Where would you find Skeletal Muscle tissues?
Attached to bones.
Where would you find Smooth Muscle tissues?
Covers walls of organs, skin, and walls of blood vessels.
Where would you find Cardiac Muscle tissues?
Heart wall
Where would you find Serous Membrane?
Inner lining of thorax and abdomen.
Where would you find Mucous Membrane?
Lines tubes and organs that open to the outside world. (Mouth, nose, throat, etc.)
Where would you find Cutaneous Membrane?
Covers the body. (Skin)
