Lab 5 Flashcards
3 bones that make up the coxal bone (pelvic girdle)
Ilium, Ischium, Pubis
4 bones that form the pelvis
right hip bone, left hip bone, sacrum, coccyx
What originates on the iliac crest
Gluteus maximus, gluteus medius, transversus abdominis
What does the head of the femur articulate with
acetabulum
What attaches to the fovea capitis
ligament of the head of the femur
What is the weakest part of the femur
the neck
Where do the gluteus medius and minimus insert
greater trochanter of femur
Where do the ilioposoas muscles insert
lesser trochanter
What muscles insert into the gluteal tuberosity of femur
Pectineus and gluteus maximus
What separates the medial and lateral condyles of femur
intercondylar fossa
3 functions of the patella
strengthens the quad muscle, protects anterior surface of knee joint, acts as pulley
what do the medial and lateral tibial condyles of tibia articulate with
the medial and lateral condyles of femur
where is the tibia tuberosity
on anterior surface of tibia, where patella attaches
What originates at the soleal line of tibia
soleus muscle
Where is soleus muscle
Muscle in back of calf to heel, plantar flexion
What does the medial malleolus of tibia do
Supports ankle joint and prevents tibia from sliding laterally
Where is the fibula with relation to Tibia
Runs parallel on lateral side
What does the head of the Fibula articulate with
The inferior posterior surface of lateral tibial condyle
What does the lateral malleolus articulate with
The talus bone
Talus bone
lower ankle bone, proximal to calcaneous (heel) bone
Calcaneous bone
heel bone
2 Tarsal bones of the Tarsus (ankle)
Talus bone and calcaneous bone (heel)
What are the names of the 5 metatarsals
Metatarsal I,II,III,IV,V (with base and head)
Which toe only has 2 phalanges
The hallux (big toe), only proximal and distal phalanges
What bony structures make up the balls of the foot
The calcaneus and the distal ends of metatarsals
the 2 joints of the Pelvis
Sacroiliac joint and pubic symphysis
Sacroiliac joint
Sacral and iliac auricular surfaces of pelvis
What type of joint is the Sacroiliac joint
Diarthrotic synovial monaxial planar joint
What stabilizes the sacroiliac joint
Sacroiliac, sacrotuberous and sacrospinous ligaments
What does the sacroiliac ligament do
connects tuberosities of sacrum and ilium
Pubic symphysis joint
public bones joined together with a fibrocartilage pad in middle
What type of joint is the pubic symphysis joint
Amphiarthrotic cartilaginous symphysis joint
3 ligaments that reinforce the articular capsule of hip
Iliofemoral, pubofemoral, ischiofemoral ligaments
Iliofemoral ligament
attaches ilium and femur
Pubofemoral ligament
attaches obturator crest and superior ramus of pubis
Ischiofemoral ligament
attaches ischium and femur
What do medial and lateral meniscus of knee do
shock absorb, collagen pads
Where does the lateral collateral ligament run
lateral side of knee- from the fibula to femur
Where does the medial collateral ligament run
medial side of knee- from tibia to femur
Function of medial/lateral menisci
Cushion femur when changing positions
Muscles/tendons that reinforce the knee joint
Popliteal, patellar, quadriceps tendon
What does the popliteal ligament reinforce
back of the knee
What is the ankle bone called
Talocrural joint
Calcaneous bone
heel bone
Talus bone
above calcaneous
Medial and lateral malleolus
ankle bones, stabilize the talocrural joint
What ligaments reinforce the talocrural joint
medial deltoid, anterior talofibular, posterior talofibular, calcaneofibular ligament
The 2 arches of the foot
Longitudinal arch (length) and transverse arch (width over)
