HBIO 301 TISSUES EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS GRADED A++ LATEST UPDATE
What are the 4 groups of tissues?
Muscle, epithelial, connective, and nervous tissues.
What are the 3 types of muscle tissue?
skeletal, cardiac, smooth
How many types of Epithelial tissue are there?
8 types, including many glands
How many types of connective tissues are there?
3-4, including many cell types.
What two types of tissues make up most membranes?
Membranes are made from connective tissue connecting to epithelial tissues.
Histology is...
The study of tissues
What is a basic definition of tissues?
They are groups of closely related cells that perform similar functions; thus, they have
similar structure.
Epithelial tissue major functions (3)
Lines passageways or exposed surfaces for protection, specialized based on task
(absorption, diffusion, sensory), and forms part of most glands.
Connective tissue major functions (4)
,Stores energy
Transports material
Supports other tissue
Fills internal spaces
Muscle tissue major functions (2)
Produce movement and heat through shivering
Neural tissue major function
Transport electrical signals between membranes
Which 2 tissue types are excitable?
Muscular and Neural
What tissues come from the ectoderm?
Epithelial: epidermis and glands of the skin (dorsal)
Nervous: Neural crest cells and PNS derivatives
What tissue types come from mesoderm?
Muscle, connective, and epithelial
What epithelial tissues come from the mesoderm?
Endothelium and mesothelium
endothelium vs mesothelium
endothelium: simple squamous epithelium lining blood vessels and heart
mesothelium: epithelial lining of the serous cavities. This is the actual type of membrane
that is called serous membranes, and it can be parietal or visceral
What tissue comes from the endoderm?
Epithelial -> lining of the GI tract and glands located nearby
, What are 6 defining characteristics of epithelial tissue?
Avascular
Innervated
Cellularity (closely packed)
Polarity (apical vs basal end)
Highly regenerative
Attachment (bound to basal lamina)
Name 2 apical structures of epithelial cells?
Cilia and microvilli
Name 4 specific cell junctions of epithelial cells
Tight junction
Gap junction
Desmosome
Adhesive belt
What are the 2 components of the basement membrane
Basal lamina and lamina reticularis
What is the function of cilia?
Move mucus across an exterior surface to aid in movement
What is the function of microvilli
increase surface area for absorption
What are the 3 specializations of epithelial cells?
