theory test 2 Flashcards
what is a synovial joint
a synovial joint is a joint capsule lined by a synoivla membrane that produces synovial fluid
synovial fluid is made to reduce friction between articular cartilage of synovial joint during movement
also contains hyaline cartilage
what is mesentery
double layer of peritoneum which attaches the vascular and nerves to the intraperitoneal organs
attaches to the abdomen wall and keeps intestine in place to reduce the intestines falling into pelvis area
what are the muscles involved in knee flexion
semitendiosus semimembranosus biceps femoris sciatic nerve posterior side of leg
list these organs
A. Liver B. Gallbladder C. stomach D. duodenum E. ascending colon F. small intestine G. Caecum H. appendix I. Sigmoid colon J. transverse colon K. rectum
Which skull bones contains a sinus
frontal
sphenoid
ethmoid
maxilla
Plantar Fascia
- protects structure sin the sole of the foot
- supports the longitudinal arches
- gives origin to several; plantar Muscles
What structures insert on the distal phalanx of the thumb
- thumb extensors and flexors
extensor pollicus longus
flexor polices longus
What nerves give sensation to the hand
ulnar
median
radial
Anterior forearm includes:
flexor digitorum profundus - flexes the fingers at all joints
extensor pollicus longus- flexes the thumb at all joints
what nerve innervates the most of the anterior compartment
median nerve
Ulnar inverted flexor capri ulnaris
action of wrist flexion and adduction
ulnar nerve
origin - medial epicondyle of humerus, olecranon and posterior border of ulna
Flexor digitorum profundus
flexes the fingers - such as the metacarpophalangeal and distal interphalangeal joints
describe the livers relationships it has with other structures
all blood leaving stomach and intestines passes through the liver
describe the functions of the liver
production of bile - helps carry away waste and break down fats in the small intestine during digestion
production of certain proteins for blood plasma
blood supply to ;liver
receives from 2 sources
hepatic artery which delivers oxgyanted blood from the general circulation
2nd is the hepatic portal vein delivering deoxygenated blood to small intestine with nutrients
what muscles contribute to elbow motion of flexion
biceps brachial
brachioradialis
musculocutaneous nerve
