What is the epicranial aponeurosis?
The galea aponeurotica (also called the galeal or epicranial aponeurosis or the aponeurosis epicranialis) is a tough fibrous sheet of connective tissue that extends over the cranium, forming the middle (third) layer of the scalp.
What does the abdominal Aponeurosis do?
The abdominal aponeurosis envelopes the abdominal muscles. It also provides the attachment sites for the external abdominal obliques, the internal abdominal obliques, and the transversus abdominus.
What is the mean of aponeurosis?
Aponeurosis, a flat sheet or ribbon of tendonlike material that anchors a muscle or connects it with the part that the muscle moves. The aponeurosis is composed of dense fibrous connective tissue containing fibroblasts (collagen-secreting spindle-shaped cells) and bundles of collagenous fibres in ordered arrays.
What are the muscles associated with the epicranial aponeurosis?
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.
Is Galea an aponeurotica fascia?
The galea aponeurotica was continuous with a superficial temporal fascia. Deep to the galea, the subaponeurotic connective tissue was bilaminar.
What is the difference between aponeurosis and Retinaculum?
Fasciae are the auxillary tissues that connect muscle to muscle while ligaments are connective tissues that connect one bone to another bone. Aponeuroses and tendons are connective tissues that connect muscles to bones.
What is the function of the Epicranial Aponeurosis?
The bellies are connected by a thick fibrous sheath called epicranial aponeurosis (galea aponeurotica) onto which both of them attach. The function of occipitofrontalis muscle is to elevate the eyebrows and wrinkle the forehead skin with its frontal part, and to retract the scalp with its occipital part.
Which is the correct definition of the epicranial aponeurosis?
ep·i·cra·ni·al ap·o·neu·ro·sis. the aponeurosis or intermediate tendon connecting the frontal and occipital belly of the occipitofrontalis muscle to form-with the temporoparietalis- the epicranius.
Which is the correct synonym for the word aponeurosis?
ep·i·cra·ni·al ap·o·neu·ro·sis. The aponeurosis or intermediate tendon connecting the frontalis and occipitalis muscles to form the epicranius. Synonym(s): galea (2) . epicranial aponeurosis. The fibrous membrane connecting the occipital and frontal muscles over the top of the skull.
Is the aponeurosis at the top of your head?
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.
Which is tendon connects the occipitofrontalis to the epicranius?
the aponeurosis or intermediate tendon connecting the frontal and occipital belly of the occipitofrontalis muscle to form-with the temporoparietalis- the epicranius.
