Answer 1

1. A,C,E are true

A.The tibial tuberosity is found on the VENTRAL (anterior) aspect of the TIBIA bone-True

Reason:The tibial tuberosity is a large oblong elevation located on the proximal, anterior aspect of the tibia, found below the region where anterior surfaces of the lateral and medial tibial condyles end.

C.The intertrochanteric line is found on the VENTRAL (anterior) aspect of the FEMUR bone-True

Reason:The intertrochanteric line is located on the anterior side of the proximal end of the femur bone.

E.The greater trochanter is found on the DORSAL (posterior) and LATERAL aspect of the FEMUR bone-True

Reason:The greater trochanter of the femur is a large, irregular, quadrilateral structure and a part of the skeletal system. It is directed lateral and medially and slightly posterior.

B is false

Reason:The Linea aspera is found on the posterior surface of the shaft of the femur

D is false;

Reason:The lateral condyle is the lateral portion of the upper extremity of tibia.

2. A,B and E are true.

A)The greater trochanter is a site of muscle attachment -True

Reason:

The greater trochanter gives attachment to many muscles like the gluteus medius and minimus, piriformis, obturator internus and externus, and gemelli muscles.

B.The linea aspera is a site of muscle attachment -True

Reason:

Linea Aspera is the longitudinal irregular crest that is composed of 2 lips,which serves as the insertion site of the adductor thigh muscle. It is the origin of various muscles in the thigh.

E .The intertrochanteric crest is a site of muscle attachment-True

Reason:

Near the center of the intertrochanteric crest is a small tubercle for the attachment of the quadratus femoris muscle.

C is false

Reason:

The intercondylar area is tesiteof ligament attachment.The anterior and posterior cruciate ligaments and the menisci attach to the intercondylar area.

D is false;

Reason:

The lateral condyle serves as the insertion for the Biceps femoris muscle.
