Anatomy and Function of Hip and Thigh Muscles

1. What is the muscle responsible for adduction of the thigh?

Sartorius

Gluteus maximus

Adductor magnus

Tensor fasciae latae

The adductor magnus is a large triangular muscle that is responsible for adduction of the thigh, while the gluteus maximus, sartorius, and tensor fasciae latae are not primarily involved in this movement.

Explanation

The adductor magnus is a large triangular muscle that is responsible for adduction of the thigh, while the gluteus maximus, sartorius, and tensor fasciae latae are not primarily involved in this movement.

2. What is the scientific name for the long, slender muscle found in the inner thigh?

Gracilis

Deltoid

Biceps femoris

Rectus abdominis

The gracilis muscle is a long, slender muscle located in the inner thigh, responsible for adduction at the hip joint.

Explanation

The gracilis muscle is a long, slender muscle located in the inner thigh, responsible for adduction at the hip joint.

3. What muscle is primarily responsible for abduction at the hip joint?

Quadriceps femoris

Gluteus medius

Hamstrings

Iliopsoas

The gluteus medius is one of the main muscles responsible for hip abduction, along with the gluteus minimus. The quadriceps femoris, hamstrings, and iliopsoas are primarily responsible for movements at the knee and hip joints.

Explanation

The gluteus medius is one of the main muscles responsible for hip abduction, along with the gluteus minimus. The quadriceps femoris, hamstrings, and iliopsoas are primarily responsible for movements at the knee and hip joints.

4. What is the largest muscle in the human body?

Biceps brachii

Deltoid

Quadriceps femoris

Gluteus maximus

The gluteus maximus is the largest muscle in the human body and is located in the buttocks. It is responsible for movement of the hip and thigh.

Explanation

The gluteus maximus is the largest muscle in the human body and is located in the buttocks. It is responsible for movement of the hip and thigh.

5. Which muscle is located in the back of the thigh?

Tensor fasciae latae

Sartorius

Rectus femoris

Biceps femoris

The biceps femoris muscle is one of the three muscles that make up the hamstrings group located in the back of the thigh. The rectus femoris, tensor fasciae latae, and sartorius muscles are located elsewhere in the body and are not part of the hamstrings group.

Explanation

The biceps femoris muscle is one of the three muscles that make up the hamstrings group located in the back of the thigh. The rectus femoris, tensor fasciae latae, and sartorius muscles are located elsewhere in the body and are not part of the hamstrings group.

6. What is the name of the muscle located on the back of the thigh?

Semitendinosus

Quadriceps

Deltoid

Soleus

The muscle located on the back of the thigh is the semitendinosus. It is one of the hamstring muscles responsible for flexing the knee joint and extending the hip joint.

Explanation

The muscle located on the back of the thigh is the semitendinosus. It is one of the hamstring muscles responsible for flexing the knee joint and extending the hip joint.

7. Which muscle is commonly known as the 'hamstring muscle'?

Sartorius

Semimembranosus

Gastrocnemius

Trapezius

The semimembranosus muscle is one of the three hamstring muscles located on the back of the thigh, responsible for flexing the knee and extending the hip. It is commonly referred to as the 'hamstring muscle' along with the semitendinosus and biceps femoris muscles.

Explanation

The semimembranosus muscle is one of the three hamstring muscles located on the back of the thigh, responsible for flexing the knee and extending the hip. It is commonly referred to as the 'hamstring muscle' along with the semitendinosus and biceps femoris muscles.
