Old Test Questions- Lymph, Skin, Respiratory Flashcards
- Which of the following are typically present in a lymphatic vessel?
A. plasma cell B. neutrophil C. macrophage D. lymphocyte E. all of the above are correct responses
D. lymphocyte
duh
12. Which region would most likely have lymphatic nodules associated with a ciliated epithelium? A. lingual tonsil B. appendix C. bronchus D. ileum E. ureter
C. bronchus
Ciliated epithelium very common in respiratory system (in respiratory mucosa, not in olfactory mucosa)
13. Which of the following would contain the largest concentration of T lymphocytes? A. palatine tonsils B. germinal center of lymphatic nodules C. paracortex of the lymph node D. Hassall' corpuscles E. Peyer's patches
C. paracortex of the lymph node
{another answer could be periarterial lymphatic sheath (PALS)}
A. palatine tonsils [B-lymphocytes]
B. germinal center of lymphatic nodules (mostly B lymphocytes)
C. paracortex of the lymph node
D. Hassall’ corpuscles [less lymphocytes, more macrophages]
E. Peyer’s patches [M-cells]
14. The red pulp of the spleen contains A. periarterial lymphatic sheath B. central arterioles C. splenic nodules D. venous sinuses E. all of the above are correct responses
D. venous sinuses
White pulp:
periarterial lymphatic sheath, Central arterioles (in nodules), and splenic/lymph nodules.
15. In the lymph nodes, lymph flows into the subcapsular sinuses from the A. trabecular sinuses B. central arterioles C. afferent lymph vessels D. efferent lymph vessels E. medullary sinuses
C. afferent lymph vessels
THYMUS DOES NOT HAVE LYMPH NODULES!
- Which cell in the epidermis captures antigens and presents them to lymphocytes?
A. keratinocytes B. Langerhans cells C. Merkel cells D. mesangial cells E. dendritic cells
B. Langerhans cells
In non-lymphatic organs = interstitial dendritic cells
In lymphoid organs = dendritic cells/follicular cells
- Which solid organ contains afferent and efferent lymph vessels?
a. tonsil
b. spleen
c. lymph node
d. thymus
e. appendix
c. lymph node
Lymph nodes are like balls along the lymph system chain.
Spleen is wrong b/c it has arterioles and venous sinues, not lymph vessels.
- Which organ has a connective tissue stroma containing large amounts of reticular fibers?
a. spleen
b. lymph node
c. liver
d. tonsil
e. all ofthe above are correct responses
e. all ofthe above are correct responses
- Which cell can function as an antigen presenting cell?
(A) Langerhans cell (B) Kupffer cell (C) dust cell (D) macrophage (E) all of the above are correct responses
(E) all of the above are correct responses
Macrophages
- Which organ has a stroma consisting of epithelial cells derived from endoderm?
a) spleen
b) thymus
c) pharyngeal tonsil
d) palatine tonsil
e) lymph node
b) thymus
- Where would you find lymph nodules with germinal centers?
A) palatine tonsil B) medulla of the thymus C) medulla of the lymph node D) red pulp of the spleen E) cortex of the thymus
A) palatine tonsil
Thymus has no lymph nodules = not B/E
Cortex of the lymph node has lymph nodules, not medulla = not C
Which cell is most involved in cell-mediated immunity? A. T-lymphocytes B. plasma cells C. B-lymphocytes D. macrophages E. reticular cells
A. T-lymphocytes
- Which organ contains a permanent collection of lymph nodules lined by stratified squamous epithelium?
A) Ilium B) bronchus C) palatine tonsil D) appendix E) pharyngeal tonsil
C) palatine tonsil
15. Lymphocytes circulating in the blood can enter the lymph node by passing between the cells of the A. lymph sinuses B. high endothelial venules C. central arterioles D. afferent lymph vessels E. thoracic duct
B. high endothelial venules
Which region contains the largest amount of B lymphocytes? A. PALS. B. cortex of the thymus C. medulla of the thymus D. lymph nodules E. paracortex of lymph nodes
D. lymph nodules
All of the following structures are a part of MALT (mucosa associated lymphatic tissue) with the EXCEPTION of the ... A. adenoids B. thymus C. appendix D. bronchus E. palatine tonsil
B. thymus
