1.
Sternocleidomasoid
Correct Answer
B. Neck
Explanation
The sternocleidomastoid muscle is located in the neck. It is a long, thick muscle that runs from the base of the skull down to the sternum and clavicle. This muscle is responsible for various movements of the head and neck, including rotation and flexion. It helps to stabilize the neck during activities such as turning the head, looking down, or lifting heavy objects. Therefore, the correct answer is neck.
2.
Trapezius
Correct Answer
A. Shoulder
Explanation
The trapezius muscle is located in the upper back and neck region, but it extends down to the shoulder area as well. It is a large, triangular-shaped muscle that helps to stabilize and move the shoulder blades. The trapezius muscle is responsible for various movements of the shoulder, such as shrugging and rotating the shoulder blades. Therefore, the correct answer is "Shoulder."
3.
Pectoralis Minor
Correct Answer(s)
A. Underneath Pectoralis Major
C. Chest
Explanation
The correct answer is "Underneath Pectoralis Major, Chest." The pectoralis minor is a muscle located underneath the pectoralis major muscle in the chest. It is responsible for various movements of the shoulder, such as pulling the scapula forward and downward.
4.
Latissimus Dorsi
Correct Answer(s)
A. On the back reverse of the abs
B. Muscles connecting the upper extremity to the vertebral column.
Explanation
The correct answer is "Latissimus Dorsi." Latissimus Dorsi is a muscle located on the back, opposite to the abdominal muscles. It connects the upper extremity (arm) to the vertebral column (spine). It extends from under the arms and attaches to the radius bone in the forearm. It does not connect to the neck.
5.
Serratus Anterior
Correct Answer(s)
A. Beside latissimus dorsi
C. Below Pectoralis Major
Explanation
The serratus anterior muscle is located beside the latissimus dorsi muscle and below the pectoralis major muscle. It is responsible for stabilizing the scapula (shoulder blade) and assisting in movements of the shoulder joint. The muscle connects to the deltoid muscle, which is involved in shoulder abduction and flexion. The given answer accurately describes the location of the serratus anterior muscle in relation to other muscles in the body.
6.
Internal Oblique
Correct Answer
A. Underneath the second pack of abdominals
Explanation
The internal oblique is a muscle located underneath the second pack of abdominals. It is one of the muscles that make up the abdominal wall. It runs diagonally from the lower ribs to the pelvis and plays a role in trunk rotation and lateral flexion. It helps to stabilize the core and supports the spine during movements such as bending and twisting.
7.
Iliopsoas
Correct Answer
C. Internal hips that allows for flexion of the hip
8.
Deep wrist and finger flexors
Correct Answer(s)
A. Flexes fingers
B. In the forearm
Explanation
The correct answer is "Flexes fingers, In the forearm". The deep wrist and finger flexors are a group of muscles located in the forearm that are responsible for flexing the fingers. These muscles work together to bend the fingers towards the palm, allowing for gripping and grasping movements. The statement about connecting to the illium and being in the thoracic region of the spine is incorrect and unrelated to the function and location of the deep wrist and finger flexors.
9.
Pectineus
Correct Answer(s)
A. Thigh flexion
B. Located middle thigh
D. Thigh adduction
Explanation
The pectineus muscle is responsible for thigh flexion and thigh adduction. It is located in the middle of the thigh.
10.
Adductor Longus
Correct Answer(s)
C. Interior of the thigh
D. Flexion of the thigh
E. Adduction of the thigh
Explanation
The adductor longus muscle is located in the interior of the thigh. It is responsible for flexion and adduction of the thigh. Flexion refers to the movement of bringing the thigh towards the torso, while adduction refers to the movement of bringing the thigh towards the midline of the body. Therefore, the adductor longus muscle plays a role in both of these movements in the interior of the thigh.
