lecture 12 Flashcards
acetabulum of the Os coxae
a cup shaped socket in the hip bone, it forms the hip joint and encloses the femur. Provides stability and function.
iliac crest of the os coxae
The uppermost portion or ridge, what we feel is our hip bone.
- stabilizes the lower limbs, attachment for many muscles like the hip flexors and hip rotators
iliac fossa
a curved surface
- provides for muscle attachment, helps connect the pelvic girdle to the thighs, the trunk, and supporting the spine
anterior superior iliac spine
Is an anterior and superior projection. Where the hip bone comes to a point on the anterior superior end.
- attachment point for many muscles
anterior inferior iliac spine
Is an anterior and inferior projection. Right under the anterior superior spine
- attachment for muscles and ligaments
greater sciatic notch
A deep notch, posteriorly. Provides passageway for the sciatic notch.
- forms the greater sciatic for mean when combined with ligaments
auricular surface
The rough surface posterior to the ileac fossa which looks like an ear. Where the sacrum and pelvis meet
- passageway for tendons and some internal vessels and nerves
ischial tuberosity
A rough, rounded inferior surface. Acts as a projection
- the primary weight bearing point when sitting down, attachment for many muscles of the posterior thigh, and the hamstrings, allows for hip movement
ischial spine
Is inferior to the greater sciatic notch, and projects medially toward the girdle to provide attachment for the sacrum.
- attachment for ligaments which control the movement of the sacrum. Also helps determine the baby’s head position during labor
lesser sciatic notch
Is located inferior to the ischial spine and is where nerves and vessels pass through.
pubis is?
pointy
- protects the bladder, intestines, and the internal sex organs
obturator foramen of the pubis
A large hole in the bone which allows for attachment of the hip muscles and ligaments.
* Hello, obturator.
- passage for nerves and blood vessels, allows for inner action of the adductor muscles responsible for thigh adduction
pubic symphysis
A tall oval flat surface has cartilage separating the two pelvic bones.
Works to stabilize the pubic bones together, allows for slight movement and absorption of shock
pubic tubercle
a bump projecting forward to allow attachment for the inguinal
- a point of attachment for the inguinal ligament and muscles
head of the femur
a ball like top (head) with a pit in the center
fovea capitis of the femur
o A point of attachment for ligaments to attach the femur to the acetabulum
neck of the femur
connects the head of the femur to the neck
greater trochanter of the femur
o Is on the proximal and lateral side, and points towards the feet.
Is much bigger than the tubercle.
- attachment point for muscles that move the hip
lesser trochanter of the femur
o Is a smaller point for attachment. Located below the greater and is on the opposite side of the bone.
Is bigger than the tubercle.
- attachment point for muscles that help with hip flexion, rotation, thigh stabilization, and lower extremity function
linea aspera of the femur
o Is a point of attachment for the hip muscles. Is in the middle of the bone shaft
- provides attachment for the muscles that extend and adduct to the thigh
lateral and medial epicondyles of the femur
articulates with the muscles
- attachment sites for the ligaments of the knee
lateral and medial condyles
articulates with the tibia
- primary articulation point for knee joint
intercondylar fossa
o Is a deep depression between the condyle and epicondyle. Is located posteriorly.
- attachment site for the ACL, and the PCL
patellar surface
a smooth surface located anteriorly which articulates with the patella
- a bone shield that protects the knee
