What is the action of sternocleidomastoid?
-
Moves eyes from side to side
-
Flexes neck, rotates head
-
Pulls mouth at corners
-
Closes Jaw
-
None of the above
Correct Answer
A. Flexes neck, rotates headExplanation
The action of the sternocleidomastoid muscle is to flex the neck and rotate the head. This muscle is located on the side of the neck and is responsible for various movements of the head and neck. It allows us to bring our chin down towards our chest and also helps in turning the head from side to side. This muscle does not have any role in moving the eyes, pulling the mouth at corners, or closing the jaw.Rate this question:

Name the muscle that closes and protrudes lips.
Correct Answer
Orbicularis OrisExplanation
The muscle that closes and protrudes the lips is called the Orbicularis Oris. This muscle is responsible for puckering the lips, as well as closing and tightening them. It encircles the mouth and allows for various movements of the lips, such as kissing, whistling, and speaking. The contraction of the Orbicularis Oris muscle helps to create different facial expressions and is essential for activities involving the use of the lips.Rate this question:

Which muscle raises the corner of mouth?
-
Zygomaticus
-
Platysma
-
Frontalis
-
Sternocleidomastoid
-
None of the above.
Correct Answer
A. ZygomaticusExplanation
The muscle that raises the corner of the mouth is the Zygomaticus muscle. This muscle is responsible for the action of smiling, as it pulls the corners of the mouth upward and outward. The other options mentioned (Platysma, Frontalis, Sternocleidomastoid) are not involved in this specific movement of the mouth.Rate this question:

What is the orgin of the frontalis?
-
Lower Eight Rib
-
Orbicularis Oris
-
Cranial Aponeurosis
-
Femur
-
None of the Above
Correct Answer
A. Cranial AponeurosisExplanation
The frontalis muscle is located in the forehead region and is responsible for raising the eyebrows and wrinkling the forehead. The cranial aponeurosis is a tough, fibrous sheet of connective tissue that covers the top of the skull and serves as the origin for the frontalis muscle. It provides a strong attachment point for the muscle and allows it to function effectively in its role of facial expression. The other options, such as lower eight rib, orbicularis oris, and femur, are unrelated to the origin of the frontalis muscle.Rate this question:

Which muscle has the orbicularis oris as an insertion point?
-
Frontalis
-
Trapezius
-
Bucinator
-
External Oblique
-
None of the Above.
Correct Answer
A. BucinatorExplanation
The orbicularis oris muscle is a circular muscle located around the mouth. It is responsible for puckering the lips and closing the mouth. An insertion point refers to the attachment of a muscle to a bone or other structure. In this case, the orbicularis oris muscle inserts into the buccinator muscle. The buccinator muscle is a thin, flat muscle located in the cheek region. It helps to compress the cheeks, aiding in actions such as blowing, sucking, and chewing. Therefore, the correct answer is Bucinator.Rate this question:

What is the orgin of orbicularis oris?
-
Mandible and Maxilla
-
Mandible and Temporal
-
Maxilla and Scapula
-
Zygomatic Bone
-
None of the above
Correct Answer
A. Mandible and MaxillaExplanation
The orbicularis oris is a muscle located around the mouth and is responsible for puckering the lips. The mandible and maxilla are the bones that make up the upper and lower jaws, respectively. As the orbicularis oris muscle surrounds the mouth, it is logical that its origin would be from both the mandible and maxilla, as stated in the correct answer.Rate this question:

What is the insertion for the Masseter?
-
Skin of Eyebrows
-
Mandible
-
Tissues around eyes
-
Maxilla
-
None of the Above.
Correct Answer
A. MandibleExplanation
The masseter is a muscle responsible for jaw movement and is located in the lower part of the face. The mandible, or the lower jawbone, is the correct insertion point for the masseter muscle. This means that the masseter muscle attaches to the mandible, allowing it to control the movement of the jaw. The other options listed, such as the skin of eyebrows, tissues around the eyes, and maxilla, are not correct insertions for the masseter muscle.Rate this question:

What muscle pulls the corner of the mouth inferiorly?
-
Masseter
-
Frontalis
-
Temporalis
-
Platysma
-
None of the Above
Correct Answer
A. PlatysmaExplanation
The platysma muscle is responsible for pulling the corner of the mouth inferiorly. It is a thin, flat muscle located in the neck region. When it contracts, it causes the corners of the mouth to pull downwards, resulting in a downward movement of the lower lip. The other muscles mentioned in the options, such as the masseter, frontalis, and temporalis, are not involved in this particular movement of the mouth.Rate this question:

What is the Orgin of Platysma?
-
Sternum
-
Sternum and Clavicle
-
Connective tissue covering of Superior Chest Muscle
-
Lower Leg
-
None of the Above
Correct Answer
A. Connective tissue covering of Superior Chest MuscleExplanation
The origin of the platysma muscle is the connective tissue covering of the superior chest muscle. This means that the platysma muscle originates from the layer of connective tissue that covers the superior chest muscle. The other options, such as the sternum, clavicle, lower leg, or none of the above, are not correct origins for the platysma muscle.Rate this question:

What muscle is the insertion for the termporal bone?
-
Orbicularis Oculi
-
Bucinator
-
Orbicularis Oris
-
Sternocleidomastoid
-
None of the Above
Correct Answer
A. SternocleidomastoidExplanation
The sternocleidomastoid muscle is not the insertion for the temporal bone. The insertion for the temporal bone is actually the temporalis muscle. The sternocleidomastoid muscle is located in the neck and it inserts into the mastoid process of the temporal bone, but it is not specifically the insertion for the temporal bone itself.Rate this question:
-
- 12.
Where is the Insertion for Masseter?
-
Occipital Bone
-
Zygomatic Process
-
Temporal bone
-
Scapula
-
None of the above.
Correct Answer
A. Temporal boneExplanation
The insertion for the masseter muscle is the temporal bone. The masseter muscle is a powerful muscle responsible for closing the jaw and is attached to the mandible (lower jaw) and the temporal bone of the skull. It originates from the zygomatic arch and inserts onto the ramus of the mandible, allowing it to exert force and facilitate movements of the jaw during chewing and biting. The occipital bone, zygomatic process, and scapula are not involved in the insertion of the masseter muscle.Rate this question:
