Explanation / Answer

1) aggregated lymphoid follicles peyers patch function in filtration of lymph they are lymphoid aggregate .they are egg shaped lymphatic nodules that are similar to lymph nodes in structure.thei main function is analyze and respond to pathogenic microbe in ileum.

2)paranasal sinus have useful functions.here answer is false

a) it reduces weight of the skull

b)it acts as a cushion against any facial trauma.

c) humidification and warming of imspired air occurs here

d)it imparts resonance to voice

e)it provide thermal regulation of vital parts of head

F)it aids in facial growth

3)the greatest amount of elastic tissue found in arteeies are located in tunica media they contain large amount of loose elastic fibers which help the arteries to stretch.

4)meningesprovide protection to spinal cord .meninges are formed of 3 layer duramater, arachnoid mater,pia mater.

5)answer is urogenital diaphragm

The boundaries of perineum are in front the arcuate ligament of pubis and pubic arch behind the apex of coccyx on either side.ischipubic ranus, and sacrotuberous ligament.

6)

Involution means shrinlage of an organ.

Invagination the action of turning inside out or folded

Ingression it is change of position or relative location of cells

Egression is an act of coming out or emergence

Regression it is the return to previous stage which may be less developed.so here invagination will be the answer.

8)the auditory tube drains into nasopharynx

It drains secretion of middle ear through mucocilliary transport system into naspharynx.

10)femoral ligament

femoral artery is formed of femoral vein and femoral artery and femoral nerve,femoral triangle forms an hollow at anterior thigh region.
