16
Q

Medial Epicondyle

A

Located at the distal end of the humerus, it is an epicondyle which points toward the middle of the body

17
Q

Radial Tuberosity

A

A tuberosity on the radius which articulates with the ulna at the radial notch

18
Q

Radial Notch

A

A notch on the ulna which articulates with the radial tuberosity

19
Q

Interosseous Membrane

A

A membrane of connective tissue which connects the radius and ulna, and the tibia and fibula

20
Q

Ulnar Notch

A

a notch on the distal end of the radius which articulates with the head of the ulna. This makes us the distal radioulnar joint

21
Q

Styloid Process

A

Located on the anterior side of both the distal radius and distal ulna, it is a process which points toward the carpals

22
Q

Radius articulates with these carpals

A

Scaphoid, Lunate, Triquetrum

23
Q

Proximal Carpals

A

Scaphoid, lunate, triquetrum, pisiform

24
Q

Distal Carpals

A

Hamate, capitate, trapezoid, trapezium

25
Q

Pelvic Girdle

A
  • Coxal bone made up of ilium, ischium, and pubic bones
  • pubic symphysis
  • sacroiliac joints
26
Q

Acetabulum

A

The socket into which the ball of the femur is inserted

27
Q

Male vs. Female Pubic Arch

A

Males generally have a pubic arch of less than 90 degrees, whereas females tend to have an arch of greater than 90 degrees. Females also tend to have wider pelvic brims for a baby to fit through

28
Q

Features of the Femur

A
  • Greater and lesser trochanters
  • Intercondylar fossa
  • Linea aspera
  • Medial and lateral condyles
  • Medial and lateral epicondyles
  • Head
29
Q

Greater and Lesser Trochanters

A
  • Two trochanters on the proximal end of the femur
  • Only trochanters in the body
  • Greater trochanter is superior
  • Lesser trochanter is inferior
30
Q

Intercondylar Fossa

A

Located between the two condyles on the distal end of the femur

31
Q

Linea Aspera

A

Roughened ridge on the posterior side of the shaft of the femur

32
Q

Medial and Lateral Condyles

A

Condyles located on the distal end of the femur, articulate with the patella and tibia

33
Q

Medial and Lateral Epicondyles

A

Epicondyles found on the distal end of the femur

34
Q

Patella

A
  • Knee bone embedded within the patellar tendon/ligament
  • Largest sesamoid bone
35
Q

Tibia

A
  • Medial to the fibula
  • Lateral and medial condyles
  • Articulates with the fibula proximally and distally, and with the talus distally
  • Tibial tuberosity
  • Medial malleolus
36
Q

Fibula

A
  • Lateral to the tibia
  • Lateral malleolus
  • Non weight bearing
37
Q

Tarsal names

A
