ANAT 100 EXAM 5 QUESTIONS AND
CORRECT ANSWERS!!
AXON
--Single, long process of a neuron
--Propogates nerve impulse towards dendrites of adjacent neuron or target organ
--Carries impulse away from the cell body
--Regardless of neuron type (e.g. pseudounipolar, bipolar, or multipolar) there will only
be one axon
What is shown in purple?
DENDRITE
--Neuronal process that carries electrical signals toward cell body
--Neurons can have up to thousands of dendrites
What is shown in purple?
NEUROGLIAL CELLS
--Performs various supportive/maintenance functions
--Aids in signal transmission between adjacent neurons
--4 types in CNS: astrocytes(most common), microglia(least common), ependymal cells and
oligodendrocytes
What is shown in purple?
NUCLEUS
--Spherical or oval organelle that contains hereditary info
What is shown in blue?
,PSEUDOSTRATIFIED (CILIATED COLUMNAR) EPITHELIUM
--Lines most of the respiatory tract
--Consists of a single layer of cells however nuclei arranged in manner suggestive of
stratified epithelium
--Nuclei closer to apical surface belong to taller ciliated cells
--Nuclei closer to basal region belong to wedge-shaped basal cells that do not reach the
surface (wedged between taller cells)
What is shown in the micrograph?
PSEUDOSTRATIFIED COLUMNAR EPITHELIUM
--All cells attached to basil lamina (extracelluar matrix that separates epithelia from the
connective tissue)
What is shown in purple?
CILIA
--Hair-like processes that project from the apical surface of the cell
--Move in wavelike pattern to move substances along surface of cell
What is shown in pink?
RETICULAR CONNECTIVE TISSUE
--Consists of thin collagen fibres (reticular fibres due to interlacing nature)
--Scattered among spaces of fibres are numerous reticular cells
--Tirssue is common in the stroma or supporting framework of many organs
--Also found in the liver, spleen, lymph nodes, red bone marrow and around blood vessels
and muscles
What is shown in the micrograph?
RETICULAR FIBRES
, --Thin filaments that form a branching, interwoven network with no commen alignment
--Thin collagen fibres arranged in thin bundles
--Lined with coating of glycoprotein
What is shown in purple?
TRANSITIONAL EPITHELIUM
--Also called uroepithelium
--Stratified epithelium with cells of variable appearance
--Consists of multiple layers
--Cells of this tissue are flattened when distended
--Cells of this tissue are dome-shaped when relaxed
--Found in urinary bladder, ureters and upper portion of male urethra
What specific type of tissue is shown in this micrograph?
SIMPLE COLUMNAR EPITHELIUM
--Found lining the GI tract where it assists in the absorption and secretion of material
--Cells are taller than they are wide
--Nuclei located in the basal region of the cell (oval shaped)
What is shown in this micrograph?
BASEMENT MEMBRANE
--Thin, extracellular layer between epithelium and connective tissue
--Consists of a basal lamina and reticular lamina
What is shown in purple?
SIMPLE CUBOIDAL EPITHELIUM
--Produces secretory products for various glands
