the pectoral region, rectus sheath and lingual region

what are the main muscles in the chest

the pectoris majiour, the deltiod, serratus anterior and the pectoris minor

the pectoris majour has 3 heads this means it has 3 oragins what are they

what is the location of the cephaic vein

runs between the pectorals majour and the deltoid

describe the edges of the pectoralis minor

serrated irrugular edges

why does the pectoralis minor have serrated edges

its attahed to the 2,3,4th ribs

what are the functions of the muscles in the lowe abdomen 

protect the visera, assist in breathing, coghing and throwing up 

what are the muscles in the lower abdomen

the external oblique, internal oblique, transverse abdomans, rectus abdomanis and pyramidalis

what muscle is shown in this image

the external obique

whats the orogins of the external oblique

a zig zag line from ribs 5 - 12

where does the external oblique insert 

inferially on the illiac crest and the xiphoid prosses 

which way do the fiers go in the external oblique

downwards (hands in pockets)

what occours when both external oblique muscles contract vs only 1 contracting

if both contract the trunk flextes if only 1 contracts it will lateraly flex the trunk

what muscle does this image show

the internal obique

describe the position of the internal oblique in relation to the external oblique

posterior to the external oblique

where does the internal oblique originate

on ribs 9-12

where does the linternal oblique insert

the midline at the linia alba also at the pubic crest

what directions do the fibers of the internal oblique run

superiolay and medialy - hands on tits

what mscle is shown in this image

the transvers abdominis

where is the transverse abdomanis located related to the internal and external obique

located posterially to the internal and external oblique

whats the insertion of the transvers abo=domalis 

on the linia alba and the pubic crest 

whats the orogin of the transverse abdomalis

the iliac crest

which way do the fibers run in the transverse abdomanlis 

transversaly 

what is an aperneurosis

tendons in the form of a sheet at the end of the muscle

which 3 muscles form an apernerosis acros the rectus abdmanils

internal and external oblique and transvers abdomanilis

what is the aperneurosis across the rectus abdomalis called

the rectus sheath

hw are the rectus abdominis organised 

muscles sperated by white lines 

what are the diffrent white lines called

linia alb, semi lunaris and tendenous intersections

what are the linia alba, semi lunaris and tendinous intersections formed by 

the aperneurosis of the abdominal muscles 

whats the orogin of the rectus abdominis

pubic symphesis

what the insertion of the rectus abdominis 

costal margin and xipoid prosses 

what is the piramidalis muscle

tiny muscles that arnt always present

where are the piramdalis attached 

inferialy at midline arrached to the linar alba 

what encloses the pyramidalis and recutas abdomalis

the tendenous rectus sheath

how is the rectus abdominus coverd at the upper ¾

coverd anterioraly by the external and internal oblique tendns and posterially by the internal and transvers muscle tendons

how is thr rectus abdominus covers on the lower ¼

coverd anterialy by the external, internal and transvers muscle tendons and only covers posterially by the transverse fascia

what does the inginal rejoin contain 

the inginal ligiment 

what the location of the inginal ligenent

streches from the anterior superior illiac spine to the pubic tuburcule

whats the location of the inginal canal

inthe anterior abdominal wall

what runs through the inguinal region in males/females 

the spermatic cord / round ligement of the uterus 

what is the anterior wall of the inguinal canal formed by 

aperneurosis of the external oblique 

what the posterior wall of the inguinal canal formed by 

the transversalis fascia

whats the roof of the inguinal canal formed by

the muscular aperneursis of the external and internal oblique, the transversalis abdomina and fascia

what is the floor of the inginal canal formed by

the inginal ligenent

what are the testes coverd by

the tunica vaginalis 

what are the 2 layers of the tunica vaginalis 

parital layer and viseral layer

when the testes decent what layers go with them

the peritonium, transvers fascia, internal obique muscle and external oblique muscle

whats the only muscle that contributes to the spermatic cord

the internal oblique

what does the internal oblique muscles name change to

the cremaster muscle

what does the name of the transvers fascia change to

internal spermatic fascia 

what does the name of the peitonium change to

tunica vagnalis
