The muscles of mastication are primarily innervated by the mandibular branch of the trigeminal nerve, also known as cranial nerve V3. This nerve supplies the muscles responsible for chewing, including the masseter, temporalis, and pterygoid muscles. These muscles play a crucial role in the process of biting and grinding food.

What is the cranial nerve supplies motor action to the muscles of mastication?
The cranial nerve that supplies motor action to the muscles of mastication is the mandibular branch of the trigeminal nerve, also known as cranial nerve V3. This nerve innervates the major muscles involved in chewing, including the masseter, temporalis, and pterygoid muscles. It plays a crucial role in the process of mastication by facilitating jaw movement.
What muscle roles your eye counter clockwise?
The primary muscle responsible for moving the eye counterclockwise is the superior oblique muscle, which is innervated by the trochlear nerve (cranial nerve IV). Additionally, the lateral rectus muscle, innervated by the abducens nerve (cranial nerve VI), assists in this movement by pulling the eye outward. Together, these muscles coordinate to achieve the desired counterclockwise rotation of the eye.
Which nerve plexus would serve the abdominal muscles?
The abdominal muscles are primarily innervated by the lower intercostal nerves, which originate from the thoracic spinal nerves. These nerves come together to form the lower thoracic intercostal nerves and the subcostal nerve, collectively contributing to the innervation of the abdominal muscles.
Which muscle is innervated by the phrenic nerve?
Diaphragm
What is the Innervation of visceral and parietal pleura?
The visceral pleura is innervated by autonomic nerves that travel with the bronchial blood vessels. The parietal pleura is innervated by somatic nerves, specifically the intercostal nerves and the phrenic nerve.
Which cranial nerve innervates all muscles of mastication?
tongue, buccal and and those controlling mandible....muscles of the lower face. mastication = the process of chewing
What three muscles are innervated by nerves?
Three muscles that are innervated by specific nerves include the biceps brachii, which is innervated by the musculocutaneous nerve; the quadriceps femoris, innervated by the femoral nerve; and the diaphragm, which is innervated by the phrenic nerve. Each of these nerves plays a crucial role in controlling muscle movement and function.
Flexor muscles in the anterior arm are innervated by what nerve?
The musculocutaneous nerve
What is the nerve supply of the muscles of facial expression?
The facial muscles are innervated by facial nerve (cranial nerve VII). In contrast, the nearby masticatory muscles are innervated by the mandibular nerve, a branch of thetrigeminal nerve (V).
What is the cranial nerve supplies motor action to the muscles of mastication?
The cranial nerve that supplies motor action to the muscles of mastication is the mandibular branch of the trigeminal nerve, also known as cranial nerve V3. This nerve innervates the major muscles involved in chewing, including the masseter, temporalis, and pterygoid muscles. It plays a crucial role in the process of mastication by facilitating jaw movement.
What muscle is innervated by the trochlear nerve?
The superior oblique muscles
What muscles are mimetic muscles?
They are facial muscles innervated by the facial nerve that, among other things, control facial expression.
Which of the following muscles is innervated by the axillary nerve?
deltoid and teres minor
Which muscles are affected by the right accessory nerve?
The sternocleidomastoid muscle (SCM) and the trapezius muscle are innervated by the accessory nerve (CN XI)
What 2 muscles are innervated by cranial nerve XII besides the 4 intrinsic lingual muscles and the 4 extrinsic lingual muscles?
Geniohyoid & Thyrohyoid as the Hypoglossal nerve is joined by fibers from C1 which supply them
What nerve causes flexion and supination at the right elbow joint?
The flexor muscles, including the biceps brachii which is both a flexor and supinator, are innervated by the musculocutaneous nerve. The supinator muscle, which assists the biceps brachii in supination, is innervated by the deep branch of the radial nerve.
What nerve is used for mastication in dobermans?
The cranial nerve responsible for moving the cheek muscles is cranial nerve V (the trigeminal nerve). However, cranial nerve IX (glossopharyngeal) and cranial nerve XII (hypoglossal) are also involved in moving the tongue, the throat for swallowing and the muscles along the floor of the jaw.
