- The branch to the Rectus femoris enters the upper part of the deep surface of the muscle, and supplies a filament to the hip-joint.
- The branch to the Vastus lateralis, of large size, accompanies the descending branch of the lateral femoral circumflex artery to the lower part of the muscle. It gives off an articular filament to the knee-joint.
- The branch to the Vastus medialis descends lateral to the femoral vessels in company with the saphenous nerve. It enters the muscle about its middle, and gives off a filament, which can usually be traced downward, on the surface of the muscle, to the knee-joint.
- The branches to the Vastus intermedius, two or three in number, enter the anterior surface of the muscle about the middle of the thigh; a filament from one of these descends through the muscle to the Articularis genu and the knee-joint. The articular branch to the hip-joint is derived from the nerve to the Rectus femoris.
- The articular branches to the knee-joint are three in number.
- One, a long slender filament, is derived from the nerve to the Vastus lateralis; it penetrates the capsule of the joint on its anterior aspect.
- Another, derived from the nerve to the Vastus medialis, can usually be traced downward on the surface of this muscle to near the joint; it then penetrates the muscular fibers, and accompanies the articular branch of the highest genicular artery, pierces the medial side of the articular capsule, and supplies the synovial membrane.
- The third branch is derived from the nerve to the Vastus intermedius.
What else can I help you with?
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.
What nerve controls quadriceps muscle group?
Femoral nerve
Which muscle is innervated by the phrenic nerve?
Diaphragm
Is the orbicularis oculi muscle innervated by the facial nerve?
Yes
What muscle is innervated by the trochlear nerve?
The superior oblique muscles
Which nerve controls the movement of the lattisimus dorsi muscle?
The muscle is innervated by Thoracodorsal nerve, from the posterior cord of brachial plexus.
Muscle inserts into the mastoid process?
Posterior Belly of Digastric Muscle (innervated by CN VII) Facial nerve Sternocleidomastoid (innervated by CN XI) Spinal accessory nerve Longissimus Capitis (innervated by dorsal rami of C3-C8 spinal nerves) Splenius Capitis (innervated by dorsal rami of middle cervical spinal nerves)
What two nerves innervate the quadriceps and hamstrings?
The quadriceps are primarily innervated by the femoral nerve, which provides motor function to this muscle group. In contrast, the hamstrings are predominantly innervated by the sciatic nerve, specifically its tibial and common fibular branches. These nerves play crucial roles in the extension of the knee (quadriceps) and the flexion of the knee and extension of the hip (hamstrings).
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 abducts the eye?
The lateral rectus muscle, innervated by the 6th cranial nerve (the Abducens)
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.
The supinator muscle is innervated by what nerves?
The supinator muscle is primarily innervated by the radial nerve, specifically the deep branch of the radial nerve. This nerve provides the necessary motor function to facilitate the supination of the forearm. Additionally, the radial nerve branches may also receive contributions from the posterior interosseous nerve, which is a continuation of the deep branch.
