The occipitofrontalis muscle (epicranius muscle) is a muscle which covers parts of the skull….Occipitofrontalis muscle.
| Occipitofrontalis | |
|---|---|
| Insertion | epicranial aponeurosis |
| Artery | frontal belly: supraorbital and supratrochlear arteries occipital belly: occipital artery |

| Actions | raises eyebrows, wrinkles forehead |
What does the occipital muscle do?
The occipitalis muscle is innervated by the facial nerve and its function is to move the scalp back. The muscles receives blood from the occipital artery.
What is the function of aponeurosis?
1. A: aponeuroses are extensions of external tendons on the surface of pennate muscles that function as insertion sites for muscle fascicles and may play a role in modulating fascicle rotation and dynamic gearing during muscle contractions.
What muscle originates at the epicranial aponeurosis?
occipitofrontalis muscle
Occiptalis muscle, frontalis muscle, and epicranial aponeurosis are collectively known as occipitofrontalis muscle. Together they draw the eyebrows up and wrinkle the forehead. The frontal belly, as seen above, originates on the epicranial aponeurosis and inserts on the skin of the eyebrow and forehead.
What type of muscle is the temporalis?
In anatomy, the temporalis muscle, also known as the temporal muscle, is one of the muscles of mastication (chewing). It is a broad, fan-shaped convergent muscle on each side of the head that fills the temporal fossa, superior to the zygomatic arch so it covers much of the temporal bone.
Which muscles assists with smiling?
Zygomatic muscles (major and minor) – move the mouth corners up and outward when we smile. Risorius – the “smile” muscle. Pulls mouth corners laterally (outward) and forms dimples in the cheeks. This muscle is not always active in all people.
How do you relax the occipital muscles?
Apply gentle pressure from your fingertips at the base of your skull. This massage can help calm tight muscles and release tension. You can also place a rolled towel under your head and neck as you lie down on your back. The pressure from the towel can provide a gentle massage.
What does occipital neuralgia feel like?
Symptoms of occipital neuralgia include continuous aching, burning and throbbing, with intermittent shocking or shooting pain that generally starts at the base of the head and goes to the scalp on one or both sides of the head. Patients often have pain behind the eye of the affected side of the head.
Is aponeurosis a muscle?
An aponeurosis is a type of connective tissue found throughout the body. Aponeuroses provide an attachment point for muscles to connect to bone, and can also envelope muscles and organs, bind muscles together, and bind muscles to other tissues. They are important for muscle movement and posture.
What is difference between aponeurosis and tendon?
What is the Difference Between Tendon and Aponeurosis? Tendon is a tough rope-like connective tissue that attaches a muscle to the bone while aponeurosis is a delicate sheath-like connective tissue that attaches a muscle to a bone.
Is galea a muscle?
Over the dome of the skull the epicranium is formed by a sheet of tendon that’s known as the galea, or galea aponeurotica. Two muscles are attached to the galea, in front, the frontalis, and behind, the occipitalis. The occipitalis muscle arises from here on the occipital bone, above the superior nuchal line.
How do you build temporalis muscle?
To actively stretch the temporalis muscle in the supine position, the patient inserts two fingers behind the lower incisor teeth and with the thumb under the chin gently pulls the mandible forward and then downward, gradually increasing the stretch. The head is stabilized by the opposite hand.
What is the function of the epicranial muscle?
The frontalis section controls movement of the forehead and eyebrows, thus enabling forehead wrinkling. The occipitalis controls backward movement of the scalp, which raises the eyebrows. The occipitalis and frontalis sections of the epicranial muscle coordinate movement with the help of a tendon that connects them. The frontalis section…
What is the function of the epicranial aponeurosis?
Just so, what is the function of the Epicranial Aponeurosis? At the top of your head is the epicranial aponeurosis. It is like a thin helmet beneath the scalp, and provides the attachment sites for the occipitofrontalis muscle, a muscle that controls the eyebrows and facial expressions. The abdominal aponeurosis envelopes the abdominal muscles.
How does the platysma and epicranius muscles work?
Function. In contrast the epicranius elevates the eyebrows and the ear. The platysma pulls the corner of the mouth laterally and downwards and tightens the skin. The auricular muscles are quite variable which is why only some people are able to voluntarily move their ears.
Which is part of the skull does the epicranius cover?
The epicranial muscle, also called the epicranius, consists of two sections and covers the forehead, top, and upper-rear portion of the skull.
