deltoid and teres minor
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.
The deltoid is innervated by the axillary nerve which originates from the ventral rami of the C5 and C6 spinal nerves, via the superior trunk, posterior division of the superior trunk, and the posterior cord of the brachial plexus.
The musculocutaneous nerve
The deltoid muscle is primarily innervated by the axillary nerve, which originates from the brachial plexus.
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).
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.
The superior oblique muscles
1- Supraspinatus and its function is to abduct the arm ,and it's innervated by the Suprascapular nerve. 2- Infraspinatus muscle and its function is to externally rotate the arm ,and it's innervated by the Suprascapular nerve. 3- Teres minor muscle and its function is to externally rotate the arm ,and it's innervated by the Axillary nerve. 4- Subscapularis muscle and its function is to internally rotate the humerus ,and it's innervated by the Upper and Lower subscapular nerve.
They are facial muscles innervated by the facial nerve that, among other things, control facial expression.
axillary nerve or known as circumflex nerve is a nerve of the human body that comes off the brachial plexus. Brachial plexus is responsible for cutaneous and muscular innervation of the entire upper limb-Drave 10
The sternocleidomastoid muscle (SCM) and the trapezius muscle are innervated by the accessory nerve (CN XI)
Geniohyoid & Thyrohyoid as the Hypoglossal nerve is joined by fibers from C1 which supply them
