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
cranial nerve I
Olfactory - smell - sensory
cranial nerce II
OPTIC - VISION - SENSORY
CRANIAL NERVE III
Oculomotor
eye movement pupillary constriction accomodation
motor
cranial nerve IV
trochlear
eye movement
motor
cranial nerve V
trigeminal - facial sensation, mastication, both sensory and motor
cranial nerve VI
abducens - eye movement motor
cranial nerve VII
FACIAL
FACIAL MOVEMENTS
BOTH
Cranial nerve VIII
VESTIBULOCOCHLEAR = hearing balance = sensory
Cranial nerve IX
glossopharyngeal
taste and sensation
elevation of pharynx/ larynx
both sensory and motor
Cranial Nerve X
Vagus
taste, speech, swallow, cough reflex
sensory and motor
cranial nerve XI
spinal accessory
head turning
motor
cranial nerve XII
hypoglossal
tongue
motor
describe the acronym for the cranial nerves
O O O To Touch And Feel A Girls Vagina So Hot
knee flexion
posterior compartment semitendinosus semimembranosus tibial portion of the sciatic nerve biceps femoris
knee extension
anterior compartment rectus femoris vvastus lateralis vastus intermedius vastus media's
why is the shoulder prone to dislocation
large range of motion - ligaments are not think
the glenoid fossa is small compared to the head of the humerus and shallow
the humerus doesn’t articulate with the axial skeleton but with the scapula both the scapula and humerus are mobile
temporomandibular joint
- synovial joint which has an intracapsular disc
capable of fine and forceful movements
allows retraction, protraction, elevation and depression of the mandible and side to side translation
Posterior forearm
brachioradials extensor carpi radialis longus and brevis extensor digitorum extensor digit minimi extensor carpi ulnaris
Elbow motion
3 ligaments ulnar collateral ligament radial collateral ligament annular ligament all three ligaments job is to offer stability to the joints
pelvis floor
female - vagina, urethra anal cavity
male- urethra anal cavity
levator ani - puborectalis, pubococcygeus and iliococcygeus
Coccygeus
contraction and relaxation of sphincters
abdominal muscles
transversus abdominis
internal oblique
rectus abdominis
external oblique
transversus abdominis
protect internal organs by holding them in place
support torso by maintaining the abdominal walls and tension
internal oblique
functions - bilaterally to flex the trunk and compress its trunk
flexing torso and spinal in abdominal region
external oblique
moves body between ribcage and pelvis
rotate trunk
works bilaterally to flex the trunk
