Lecture 13 Flashcards
what are the movement of the hip joint
- flexion/ extension
- abduction/ adduction
- rotation
what are the movements of the knee
-flexion/extension
What are the movements of the ankle
- dorsi flexion, plantar flexion
- Inversion/eversion
what are the movements of the toes
-flexion/extension
adduction/abduction
___________ attaches to th lower limb and axial skeleton to support visera
pelvic girdle
Pelvic girdle is intended for __________________
stability rather than motion
_________________ articulates posteriorly with the sacrum (axial skeleton) and anteriorly with each other
pelvis
What are the innomkiate bones
coxal bones
What are the 3 coxal bones
ischium, illiium, pubis
__________ relative to the pelvic brim
outlets
____________ superior, is an incomplete ring
false pelvis
_____________- inferior, complete bony ring
True pelvis
_____________ is the joint made of the head of the femurs and the acetabulum of the pelvis
hip joint
head of the femur
the ball
the acetabulum of the pelvis
the socket
The leg refers to
below the knee
_______________ largest bone in the body and is the hardest to break
femur
____________ most complex joint in the body. between the tibia and the femur
knee joint
The knee joint is a bad _____________
hinge joint
_____________ are the fibrocartilages that absorb the shock to the joint
menisci
what are the two kinds of ligaments
- collateral
- cruciates
what are the two types of collateral ligaments
- medial collateral
- lateral collateral
what are the two types of cruciate ligaments
- anterior cruciate
- posterior cruciates
What do the collateral do
stop the rocking of the knee joint
What do the cruciate do
stop the sliding of the knee joint
_____________ act to make a larger moment arm for the quadriceps muscles
patella
___________ contact from the lower lateral side of the knee joint
knee injury
What are the unhappy triad
medial collateral ligament
anterior cruciate ligament
medial meniscus
____________- sits on the femur, is the majority weight bearing bone
tibia
___________________ important bone for ankle formation
fibula
_________ is digits 1 of the foot
hallox
__________ are the true ankle joints
talus
______________ heal of the foot joint
calcareous
what are the two tarsal joints that allow for inversion and eversion
- transverse tarsal
- subtalar joints
What is the transverse tarsal joint made of
- calcaneous joint
- talanavicular joint
What is the subtler joint
between the tallus and calcaneus
____________ are transverse and longitudinal and help in walking by storing energy
arches
What are the 4 ligaments that maintain the arches
- plantar aponeurols
- long plantar ligament
- short plantar ligament
- plantar calcaneonavicular ligament
What are the chewing muscles
muscles of mastication
________________ work to raise and lower mandible
muscle of mastication
What are the movements and innervation of muscles of mastication
- lateral and anterior movements
- Innervated by cranial nerve 5
- opening of the jaw, mostly passive
_______________ on the temporal fossa raises the jaw
temporalis
________ raises, medial/ lateral rotation, and anterior and posterior movements of the jaw
masseter
______________ pull jaw forward
pterygoids
What is the origin of the termporatis
temporal fossa
What is the insertion of the tempyoalis
coronoid process of the mandible
What is the origin of the masseter
on zygomatic arch
What is the insertion of the masseter
ramous of mandible,
lateral angle of mandible
What is the origin of the pterygoids
lateral sphenoid
What is the insertion of the pterygoids
medial angle of mandible
