Question

caudal most branchial adductor muscle innervation

Answer 1

The adductors are layered muscles that fan out from the small area of attachment on the pubic bone toward the femur.

There are three muscles in this group whose names start with the word, adductor. We’ve covered adductor magnus in a previous post, so we’ll just take a look at adductor brevis and adductor longus.

The word adductor describes the action of these muscles.

Adductor comes from the Latin words “ad” which means “toward” and “ducere” which means “to lead”.

The second word in these two muscle names refers to the size of the muscle.  

The word brevis is a Latin word meaning short.

The word longus is a Latin word meaning long.

You could put the words together then to get an understanding of the size and action of each muscle.

Adductor brevis is“a short muscle that leads something toward the body”.

Adductor longus then is “a long muscle that leads something toward the bone.

Pectineus assists in both adduction and flexion of the femur at the hip joint.

The primary function of adductor brevis is adduction of the thigh at the hip joint. Additionally, Adductor brevis assists in flexion and medial rotation of the femur at the hip joint.

The primary action of Adductor longus is adduction of the thigh at the hip joint. It also assists in flexion and medial rotation of the femur at the hip joint.

The primary action of Gracilis is adduction of the thigh. It also assists in flexion of the knee and medial rotation of that flexed knee.
