ANAT 100 EXAM 4 QUESTIONS AND
CORRECT ANSWERS!!
CEREBRAL HEMISPHERE
--Cerebrum divided into two hemispheres
--Hemispheres separated by falx cerebri which extends between hemispheres in
longitudinal fissure
--At the base of the fissure, the two hemispheres are connected by the corpus callosum
(large fibre tract of neurons; white matter)
The following image shows a zoomed in anterior view of the base of the brain. What structure is
shown coloured?
COLLAGEN FIBRES
--Strong proteins that are the main organic component of connective tissue
--Principal building block in body tissues
--Help tissues resist tensile loads
--Flexible and have a high tensile strength (triple helix)
What is shown in pink?
SIMPLE SQUAMOUS EPITHELIUM
--Epithelial layer one cell thick
--Cells are flat, thin and somewhat irregular in shape
--Lines blood vessels to maximize energy efficiency and to increase the speed at which
material is exchanged
What tissue type does this micrograph show?
, CONNECTIVE TISSUE
--One of the most abundant of the four types of tissues
--Consists of relatively few cells in a variable matrix
--Functions as a binding and supporting tissue within the body
--Matrix can range from a fluid extracellular environment, to a gel-like substance / hard
mineralized material
What is shown in purple?
ADIPOSE CONNECTIVE TISSUE
--Section of adipose tissue from the epicardium of the heart
--Tissue specialized for energy storage
--This is also an example of loose connective tissue
--More ground substance and less CT fibres
--Can be found almost everywhere in the body, especially if an individual becomes
excessively obese.
--Adipocytes have characteristic signet-ring appearance
--Large fat vacuole within the cytoplasm of the cell displaces the nucleus and other
organelles to the periphery of the cell.
What structure is shown here?
NUCLEI
--Spherical or oval organelles
--Contains hereditary factors of cell (genes)
What is shown in purple?
LIPID DROPLETS
