Tissues Flashcards
What are the two main types of nervous tissue?
Neurons and glia
What are the three main anatomical structures of a neuron?
• Dendrites
• Soma
• Axon
What are the three main features of nervous tissue?
• Conduct nerve impulses
• Vascular
• Low mitotic rate
What are the three main functions of neurons?
• Receive stimuli
• Transmit electrical impulses across distances
• Control muscle activity
BONUS
There are six types of glial cells, can you name four?
Astrocytes
Oligodendrocytes
Microglia
Ependymal cells
Schwann cells
Satellite cells
What are the three types of muscle tissue and their locations?
•Cardiac- the heart
•Skeletal- attached to bones, eyelids, tongue, urethra, anus
•Smooth- walls of Hollow organs
What are three types of muscle tissue and their specific features?
•Cardiac: striated and branched, involuntary
•Skeleton: multinucleated and striated, voluntary
•Smooth: no striations and arranged in sheets involuntary
Which type of membrane protects against dehydration, immune, and physical barrier?
Cutaneous
What is the function and 3 main features of muscle tissue?
Function: contraction to create change in body and/or organ
Features
• Innervated
• Vascular
• Typically slow mitotic rate
What are the functions of the three types of membranes?
•Mucus membrane: absorption, secretion, protection
•Serous membrane: produce watery fluid, reduce friction
•Cutaneous membrane: protection against dehydration, immune, and physical barrier
What is the mucous membrane composed of?
epithelium, connective tissue, and often smooth muscle-typically contains glands
Name seven types of epithelial tissue?
simple squamous
stratified squamous
simple columnar
simple cuboidal
stratified cuboidal
pseudostratified ciliated columnar
transitional
Name two classifications of glands and how they release their secretions?
Exocrine glands: secretions into ducts that lead to the body surface or body cavities
Endocrine glands: secretions into the blood
Name five distinguishing features of epithelial tissue?
-closely packed cells (typically tight junctions)
-sit on the basement of membrane
-avascular
-good nerve supply
-high mitotic rate
Which type of membrane produces a watery fluid, and reduces friction?
Serous membrane
Which Cartlidge type has a firm matrix, supports and reinforces?
Hyaline-resists compressive stress
2 Components of connective tissue
•cells (immature names end in blast; mature names end in cyte-)
•extracellular matrix (ground substance and fibers)
What characteristic does fibrocartilage have?
Absorbs comprehensive shock
Which Cartlidge maintain shape while allowing for flexibility?
Elastic-maintains shape
Which membrane deals with absorption, secretion, and protection?
Mucous membrane
Name three types of fibers in connective tissue
Collagen
Reticular
Elastic
Which connective tissue is the strongest, providing tensile strength?
Collagen
Which connective tissue is short, fine, branched?
Reticular
Which type of epithelial tissue is found in the uterus, bladder, and parts of the urethra?
Transitional
