Smooth Muscle
Skeletal Muscle - Longitudinal
What type of muscle and what kind of cut is arrow pointing to?
Skeletal muscle of tongue - pointing to cross-sectional (tend to look more circular). Bottom is longitudinal
What type of muscle is this and what is circled
Cardiac - intercalated disks
What type of muscle is this
Cardiac - dark bands are intercalated disks
Name muscle on left and right
Left is cardiac and right is skeletal
Cardiac Muscle
Skeletal Muscle
Smooth Muscle
What are these
secondary lymphoid follicles with germinal centers on palantine tonsils woot woot
What are the arrows on the left pointing to? The right?
Left - germinal centers, 2nd lymphoid follicles; right - crypts
simple squamous epithelium of a tonsil where APCs would be found! yay!
Lymph node. In blue the subcapsulary sinus. In red, afferent vessels within capsule
Lymph node - medullary cords surrounding medullary sinuses
What is the large ridge in the middle of this picture?
Paratrabecular sinus in lymph node!
Name structures indicated
1) Capsule 2) Afferent Vessel
What tissue is this? What is circled and what is arrow pointing to?
Spleen, trabeculae is circled, arrow points to capsule
Name all these structures:)
1 - cortex
2 - paracortical zone
3 - medulla
4 - medullary cords
5 - lymphoid follicle of the cortex
6 - capsule
7 - subcapsular sinus
8 - cortical sinus
9 - medullary sinus
This is a lymph node
What tissue is this
This is a spleen. The white pulp is white and the red pulp is red. Crazy.
Splenic cord in orange. Splenic sinus in yellow. SPLEEN.
Silver Stain of Spleen
What does this lobular structure represent
THE THYMUS!
What are arrows pointing to
epithelial reticular cells of the thymus
Light purple vs dark purple
light purple is intima, dark purple is media - aorta
1) endothelium, 2) intima, 3) media, 4) adventitia
This is the aorta. What’s the arrow pointing to
vasa vasorum in tunica adventitia
This is the aorta. Name numbers.
2 is tunica adventitia. 4 is adipocytes. 3 is fenestrated membranes of tunica media
1) arteriole, 2) venule, 3) capillary
Dental pulp mesenchyme
1) endocardium, 2) myocardium, 3) coronary artery, 4) coronary vein, 5) epicardium, 6) subepicardial adipose tissue
What is this
capillary
Mesentery?
1) olfactory epithelium; 2) endothelial cell nucleus; 3) sinusoid
What is this. Name layers from top to bottom.
Vena Cava. Tunica adventitia (contains cardiac muscle), tunica media with smooth muscles and tunica intima
This is cardiac muscle.
1) endothelium, 2) endocardium, 3) purkinje fibers, 4) myocardium
This is also cardiac muscle.
1) endothelium, 2) cardiac skeleton, 3) purkinje fibers, 4) myocytes
skeletal muscle - peripheral nuclei
Cardiac Muscle - Central nuclei
Cardiac Muscle
ANP
Purkinje Fibers of heart
smooth muscle - oval nucleus, centrally located
