APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The pectineus muscle originates from the pectineal line of the pubic bone and inserts into the pectineal line of the femur, or thigh bone.

Detailed explanation-2: -The pectineus muscle (/pɛkˈtɪniəs/, from the Latin word pecten, meaning comb) is a flat, quadrangular muscle, situated at the anterior (front) part of the upper and medial (inner) aspect of the thigh.

Detailed explanation-3: -The adductor magnus is the largest of the adductor muscles and is the most posterior of the adductor muscles, crossing into the posterior compartment. The adductor portion originates from the inferior ramus of the pubis and inserts on the linea aspera and the medial supracondylar ridge.

Detailed explanation-4: -Nerve supply The pectineus is considered a transitional muscle between the anterior thigh and medial thigh; this is due to innervation mainly from the femoral nerve and also sometimes from the obturator nerve.
