Chapter 3 Flashcards
4 basic types of tissues in the human body
Nervous
Connective
Epithelial
Muscle
Two types of epithelial tissue locations?
Covering and lining epithelia - found on external and internal surfaces
Glandular epithelia - secretory tissue in glands
Transitional epithelium
- resembles both stratified squamous and stratified cuboidal
- stretches readily and permits distension of lined structures
Stratified cuboidal epithelium
Typically consists of two cell layers
Only found in some sweat and mammary glands
- protective tissue
Stratified columnar epithelium
Found in male urethra, and some glandular ducts
- secretes and protects
Stratified squamous epithelium
- a thin membrane composed of several layers
- has a keratinized and non-keratinized type
- protects against abrasion
- lines esophagus, mouth and vagina
Pseudostratified columnar epithelium
A single layer of differing heights, with some not reaching the free surface
- secretes mucus, the ciliated tissue moves mucus
- upper respiratory tract
Simple columnar epithelium
A single layer of tall cells with round to oval nuclei
- absorbs and secretes mucus and enzymes
- small intestine, bronchi, uterine tubes
Simple cuboidal epithelial
A simple layer of cube-like cells with large, spherical central nuclei
- secretes and absorbs
- ducts, kidney tubules
Simple squamous epithelium
Single layer of flattened cells with disc-shaped central
- allows territorials to pass through by diffusion and filtration and secretes a lubricating substance
- air sacs of lungs and lining of the heart
Connective tissue 4 classes
Most abundant and widely distributed tissue type in the human body
- connective tissue proper
- cartilage
- bone tissue
- blood
4 Major functions of connective tissues
- binding and support
- protection
- insulation
- transportation
3 types of cartilage
Hyaline
Elastic
Fibrocartilage
Types of muscle tissue
Smooth
Cardiac
Skeletal
merocrine glands
secrete their products by exocytosis
- sweat, salivary glands
holocrine glands
products are secreted by rupture of the glands
-sebaceous glands
another word for serous membranes
serosae
hyaline cartilage
cushioning properties
forms most of embryonic system
covers ends of long bones in joint cavities
fibrocartilage
tensile strength with ability to absorb compressive stress
in intervertebral discs, pubic symphysis, menisci of knee joint
skeletal tissue
- long cylindrical fibers
- voluntary movement, produces heat, protects organs
- attached to bones and skin
cardiac tissue
- short, branched fibers
- contracts to pump blood
smooth tissue
short, spindle-shaped fibers
- involuntary movement, blood flow, secretions, regulates airway
- walls of hollow organs
epithelial tissue membranes
cutaneous membranes
mucous membranes or mucosae
serous membranes or serosae
cutaneous membranes
cover outside of body
