Answer:
The correct answer is option C. thymus.
Explanation:
Lymph nodules are small groups of lymphoid tissue present in the loose under the wet epithelial membranes such as the digestive system, urinary bladder, and respiratory system.
The thymus does not contain lymph nodules like other lymphatic organs such as spleen, tonsils and lymph node. However, small lymphocytes known as thymocytes are grouped together in the cortex and epithelial reticular cells can appear like nodules in the medulla.
Thus, the correct answer is option C. thymus.
C. MHC (MajorHistocompatibility Complex)); T cell receptors
Answer:
types 4,8,10
Explanation:
1.
Fibril-forming collagens (I, II, III, V, XI, XXIV, XXVII);
2.
Fibril-associated collagens with interrupted triple helices (FACITs) (IX, XII, XIV, XVI, XIX, XX, XXI, XXII). The FACITs do not form fibrils by themselves but they are associated with the surface of collagen fibrils.
3.
Network-forming collagens (IV, VIII, X) form a pattern in which four molecules assemble via their amino-terminal 7S domain to form tetramers while two molecules assemble via their carboxy-terminal NC1 domain to form NC1 dimers
4.
Membrane collagens (XIII, XVII, XXIII, XXV)
