Exam 2: Lower Limb lecture ii Flashcards
tibia: lateral and medial condyles articulate w/
femoral condyles
tibia: intercondylar tubercles paired extensions that form the _
intercondylar eminence
tibia: the intercondylar eminence, which in turn separates the two _ surfaces
the two articular surfaces
tibia: intercondylar tubercles - the tubercles (and areas near them) provide attachment for the _ and _ ligaments of the knee
menisci and major ligaments of the knee
tibia: the sharp _ border and the _ surface form the “shin”
sharp anterior border and medial (anteromedial) surface
tibia: tibial tuberosity attachment point for _ ligament
patellar ligament
tibia: fibular articular facet (anterolateral/posterolateral?); articulates with
posterolateral; articulates w/ head of the fibula
tibia: medial malleolus extends _ to the rest of the shaft; provides attachment for _ joint ligaments; its lateral surface articulates w/ the _
extends inferior
for ankle joint ligaments
the talus
tibia: interosseous border attaches _ that unites tibia and fibula
interosseous membrane
tibia: soleal line attachment of
soleus
tibia: nutrient foramen; these are also present on other bones, passageway for a _ supplying bone tissue
blood vessel
fibula: tibiofibular syndesmosis joint attaches fibula to _ and includes the _
tibia and includes interosseous membrane
fibula: head of fibula articulates w/
tibia
fibula: shaft of fibula site of attachment for
many muscles
fibula: lateral malleolus provides attachment for _ and articulates w/ _
attachment for ankle joint ligaments and articulates w/ talus
what are the bones that make up the tarsus (7)
- talus
- calcaneus
- navicular
- cuboid
- medial (1st) cuneiform
- intermediate (2nd) cuneiform
- lateral (3rd) cuneiform
only the _ articulates with leg bones
talus
the _ transfers some weight to the calcaneus, and some to the forefoot via a “hammock” that is suspended across a gap btwn a shelf-like projection of the calcaneus (the sustentaculum tali) and the navicular bone
this “hammock” is formed from the _
talus, formed from the plantar calcaneonavicular ligament
calcaneus: transmits the majority of the body’s weight from the _ to the _
talus to the ground
calcaneus: articulates w/
talus and cuboid
calcaneus: includes _, a ridge that lies btwn and is needed for the fcn of the tendons of the fibularis longus muscle and fibularis brevis muscle
fibular trochlea
calcaneus: includes _ tali
sustentaculum tali
calcaneus: includes the weight-bearing _ tuberosity
calcaneal tuberosity
navicular: navicular tuberosity is the site for attachment of _ that support the foot’s longitudinal arch
tendons
cuneiforms: all 3 articulate w/ the _; lateral cuneiform also articulates with the _
navicular, cuboid
tibia articulates w/ the _ and receives all the weight from it and then the tibia transfers all of that weight to the _
femur, talus
how many ankle bones?
7
how many foot phalanges
14
bones of metatarsus: the metatarsals are numbered 1-5 from_ to _
medial to lateral
bones of metatarsus: each has a proximal _ (articulates w/ cuneiform or cuboid to form _ joint), a middle _, and a distal _ (articulates w/ a proximal phalanx)
proximal base, tarsometatarsal joint, middle shaft, distal head
bones of metatarsus: tuberosity of the 5th metatarsal a site for _ attachment; projects _ over the cuboid
tendon attachment, projects laterally over the cuboid
bones of metatarsus: _ and _ bones found on the plantar surface of the head of the 1st metatarsal
medial and lateral sesamoid bones
bones of metatarsus: medial and lateral sesamoid bones are embedded in _ passing along the foot’s plantar surface
embedded in tendons
bones of metatarsus: _ line is an oblique line formed by the tarsometatarsal joints; it joins the midpoints of the medial and (shorter) lateral borders of the foot
tarsometatarsal line
bones of toes (phalanges): numbered 1 through 5 _ to _
medial to lateral
bones of toes (phalanges): each digit has a _, _, and _ phalanx except the _ which lacks the _ phalanx
each digit has a PROXIMAL, MIDDLE, and DISTAL PHALANX except the GREAT TOE which lacks the MIDDLE PHALANX
bones of toes (phalanges): each phalanx has a proximal _, a middle _, and a distal _
proximal base, middle shaft, and a distal head
tarsals composed of what bones (5)?
tarsus = ankle
- talus
- calcaneus
- navicular
- medial, intermediate, lateral cuneiforms
- cuboid
how many metatarsals?
5
how many phalanges?
3: proximal, middle (absent in great toe), and distal
lower limb fascia: fascia lata is the _ fascia of the thigh
deep fascia of the thigh
lower limb fascia: fascia lata encloses the _ muscles
large thigh muscles
lower limb fascia: fascia lata limits outward bulging of _ and thereby facilitates _ in deep veins
outward bulging of muscles and thereby facilitates venous return in deep veins
first thing to encounter after skin is
fascia (after subcutaneous tissue)
fascia lata gives rise to
septa (septa = wall) that separate muscles with similar function and innervation into compartments
lower limb fascia: fascia lata includes _ that separate muscles with similar fcn and innervation into compartments
septa
lower limb fascia: fascia lata laterally, is thickened by additional reinforcing fibers to form the _
iliotibial tract
lower limb fascia: fascia lata the iliotibial tract runs from _ to _ and is the shared aponeurosis of the _ and _
runs from ilium to tibia and is the shared aponeurosis of the tensor fasciae latae and gluteus maximus muscles
