1.
What is the origin of the Biceps Brachii?
Correct Answer
D. Scapula
Explanation
The origin of the Biceps Brachii is the Scapula. The Biceps Brachii is a muscle located in the upper arm and it has two heads, the long head and the short head. The long head originates from the supraglenoid tubercle of the scapula, while the short head originates from the coracoid process of the scapula. These origins allow the Biceps Brachii to attach to the humerus bone in the upper arm and contribute to movements such as flexion at the elbow and supination of the forearm.
2.
What is the insertion of the Biceps Brachii?
Correct Answer
B. Radial tuberosity of radius
Explanation
The insertion of the Biceps Brachii is the radial tuberosity of the radius. This means that the tendon of the Biceps Brachii muscle attaches to a bony prominence on the radius bone in the forearm.
3.
What is the origin of the Biceps Femoris?
Correct Answer
A. Parts of pelvic girdle
Explanation
The origin of the Biceps Femoris is in the parts of the pelvic girdle. This means that the muscle originates from the bones of the pelvic girdle, which includes the ilium, ischium, and pubis. These bones are located in the lower part of the torso and are important for providing stability and support to the body. The Biceps Femoris is one of the muscles in the hamstring group and plays a role in flexing the knee joint and extending the hip joint.
4.
What is the insertion of the Biceps Femoris?
Correct Answer
B. Tibia & Fibula
Explanation
The insertion of the Biceps Femoris is the Tibia & Fibula. This means that the muscle attaches to these two bones. The Biceps Femoris is one of the hamstring muscles located in the back of the thigh. It originates from the ischial tuberosity of the pelvis and inserts into the head of the fibula and the lateral condyle of the tibia. This muscle is responsible for flexing the knee and extending the hip joint.
5.
What is the origin of the Gastrocnemius?
Correct Answer
D. Femur
Explanation
The origin of the Gastrocnemius muscle is the femur. This muscle is located in the calf region of the leg and is responsible for plantar flexion of the foot. It attaches to the posterior surface of the femur, specifically the medial and lateral condyles. The other options mentioned in the question, such as the olecranon process of the ulna, lower portion of the vertebral column, and mastoid process of the temporal bone, are not related to the origin of the Gastrocnemius muscle.
6.
What is the insertion of the Gastrocnemius?
Correct Answer
C. Calcaneus bone via achilles tendon
Explanation
The insertion of the Gastrocnemius muscle is the calcaneus bone via the Achilles tendon. The Gastrocnemius is a large muscle located in the calf of the leg. It originates from the femur and crosses the knee joint. The muscle then tapers down into the Achilles tendon, which attaches to the calcaneus bone in the heel. This insertion allows the Gastrocnemius muscle to exert force on the heel, enabling movements like plantar flexion of the foot.
7.
What is the origin of the Triceps Brachii
Correct Answer
B. Scapula & Humerus
Explanation
The origin of the Triceps Brachii muscle is the Scapula and Humerus. This means that the muscle attaches to these two bones. The Scapula is the shoulder blade bone, while the Humerus is the bone in the upper arm. The Triceps Brachii is a large muscle located at the back of the upper arm and is responsible for extending the elbow joint.
8.
What is the insertion of the Triceps Brachii
Correct Answer
A. Olecranon process of ulna
Explanation
The insertion of the Triceps Brachii is the Olecranon process of ulna. The Triceps Brachii is a muscle located on the back of the upper arm and is responsible for extending the elbow joint. The Olecranon process is a bony prominence at the top of the ulna, which is one of the two bones in the forearm. When the Triceps Brachii contracts, it pulls on the olecranon process, causing extension of the elbow joint.
9.
What is the origin of the Masseter?
Correct Answer
C. Zygomatic bone & maxilla
Explanation
The origin of the Masseter muscle is the zygomatic bone and maxilla. The Masseter muscle is a powerful muscle responsible for the movement of the jaw during chewing. It originates from the zygomatic arch of the skull, which is formed by the zygomatic bone and the maxilla. The muscle then inserts into the mandible, allowing it to exert force and close the jaw.
10.
What is the insertion point of the biceps brachii muscle?
Correct Answer
B. Radial tuberosity
Explanation
The biceps brachii muscle originates from the scapula at two points (the coracoid process and the supraglenoid tubercle) and inserts at the radial tuberosity on the radius bone. This insertion allows the biceps brachii to perform functions such as flexing the elbow and supinating the forearm. The scapula, clavicle, and olecranon process are associated with other muscles and functions.
11.
What is the origin of the Sternocleidomastoid?
Correct Answer
A. Sternum
Explanation
The origin of the Sternocleidomastoid muscle is the sternum. This muscle is located in the front of the neck and extends from the sternum (breastbone) to the clavicle (collarbone) and mastoid process of the temporal bone in the skull. It helps in the movement of the head and neck, including rotation and flexion.
12.
What is the point of insertion of the Sternocleidomastoid?
Correct Answer
D. Mastoid process of the temporal bone
Explanation
The Sternocleidomastoid muscle is a long muscle located in the neck. It originates from two points: the sternum and the clavicle. It inserts into the mastoid process of the temporal bone, which is located behind the ear. This insertion point allows the muscle to have a strong attachment and provides it with the ability to rotate and flex the head and neck. Therefore, the correct answer is the mastoid process of the temporal bone.
13.
What is the origin of the Trapezius?
Correct Answer
B. Vertebral Column
Explanation
The Trapezius muscle originates from the vertebral column.
14.
What is the insertion of the Trapezius?
Correct Answer
C. Clavicle & Scapula
Explanation
The insertion of the Trapezius muscle is the Clavicle and Scapula. This means that the Trapezius muscle attaches to and inserts into the Clavicle and Scapula bones. The Trapezius muscle is a large muscle located in the upper back and neck region. It helps to move and stabilize the shoulder blades, as well as assist in movements such as shrugging the shoulders and tilting the head.
15.
What is the origin of the Latissimus Dorsi?
Correct Answer
D. Lower portion of vertebral column
Explanation
The origin of the Latissimus Dorsi muscle is the lower portion of the vertebral column. This muscle originates from the spinous processes of the lower thoracic and lumbar vertebrae, as well as the supraspinous ligament and the posterior iliac crest. It then inserts into the upper part of the humerus bone.
16.
What is the insertion of the Latissimus Dorsi?
Correct Answer
C. Humerus
Explanation
The insertion of the Latissimus Dorsi is the Humerus. The Latissimus Dorsi is a large muscle located in the back that extends from the lower spine to the upper arm. It originates from the thoracic and lumbar vertebrae, wraps around the side of the body, and inserts into the anterior surface of the humerus bone. This muscle plays a significant role in movements involving the shoulder joint, such as pulling the arm down and back, as well as rotating the arm inward.
