Muscles
Name the 3 types of muscle tissues
Skeletal, Smooth, and Cardiac.
What convey sensory stimuli from internal/external environments?
Neurons (nerve cells)
True or False: Arteries are more numerous than veins.
False
What class of glands produces hormones?
Endocrine glands
In arteries, what predominates?
Tunica media
What band in a sarcomere contains both actin & myosin?
A band
What are the CT coverings (meninges) of the CNS?
Dura mater, arachnoid, and pia mater.
Layer of a blood vessel wall that contains CONNECTIVE TISSUE only
Tunica adventitia
Simple coiled tubular glands produce what?
sweat
What vessel exhibits a lumen with an irregular profile and can posses valves?
What band(s) shorten during contraction?
H & I bands
(A band remains the same length)
Describe the direction of impulse in a neuron
From the receiving end (dendrites) to the transmitting end (axon terminals)
What are the channels between adjacent cells that provide metabolic and electrical (ionic) coupling, allowing cells to act as a SYNCYTIUM (“as one”) called?
Gap junctions
What salivary gland produces serous secretions only?
Parotid
(submandibular and sublingual glands produce BOTH mucous and serous secretions)
What type of vessel is the location of nutrient/waste exchange?
capillary
What is the CT wrapping that surrounds individual muscle fibers?
Endomysium
What neuron(s) mediates motor/efferent or association/integrative functions?
Multipolar neurons
What epithelium lines external/exposed surfaces subject to injury, high wear & tear?
Stratified squamous keratinized (dry) epithelium
What type of duct is located within a gland lobule?
Intralobular duct
(Interlobular is located within a CT septum)
What type of artery displays prominent internal and external elastic laminae?
Muscular (medium) arteries
Where is smooth muscle found?
In the walls of hollow organs and vessels (associated with the viscera)
Each of which type of cell forms only one internode segment on one axon in the PNS?
Schwann cell
Surface cells of __________ epithelium are dome shaped when the bladder is empty, squamous shape when it is fully distended.
Transitional
True or False: Exocrine glands maintain attachment with the epithelial surface from which they invaginated
True
(they do not lose their attachment)
What type of capillary promotes high levels of transport across the endothelium?
Fenestrated capillary
(continuous capillary does not display pores in the endothelium)
