Temporoparietalis Muscle
The temporoparietalis muscle is a distinct muscle of the head. It lies above the auricularis superior muscle. It lies just inferior to the epicranial aponeurosis of the occipitofrontalis muscle. The temporoparietalis muscle may be used in reconstructive Plastic surgery is a surgical specialty involving the restoration, reconstruction or alteration of the human body. It can be divided into two main categories: reconstructive surgery and cosmetic surgery. Reconstructive surgery includes cranio ... ear surgery.

Auriculares Muscles
The outer ear, external ear, or auris externa is the external part of the ear, which consists of the auricle (anatomy), auricle (also pinna) and the ear canal. It gathers sound energy and focuses it on the eardrum (tympanic membrane). Structure Auricle The visible part is called the auricle (anatomy), auricle, also known as the pinna (anatomy), pinna, especially in other animals. It is composed of a thin plate of yellow elastic cartilage, covered with integument, and connected to the surrounding parts by ligaments and muscles; and to the commencement of the ear canal by fibrous tissue. Many mammals can move the pinna (with the auriculares muscles) in order to sound localization, focus their hearing in a certain direction in much the same way that they can turn their eyes. Most humans do not have this ability. Ear canal From the pinna, the Sound#Waves, sound waves move into the ear canal (also known as the ''external acoustic meatus'') a simple tube running through to the ...

Galea Aponeurotica
The epicranial aponeurosis (aponeurosis epicranialis, galea aponeurotica) is an aponeurosis (a tough layer of dense fibrous tissue). It covers the upper part of the skull in humans and many other animals. Structure In humans, the epicranial aponeurosis originates from the external occipital protuberance and highest nuchal lines of the occipital bone. It merges with the occipitofrontalis muscle. In front, it forms a short and narrow prolongation between its union with the frontalis muscle (the frontal part of the occipitofrontalis muscle). On either side, the epicranial aponeurosis attaches to the anterior auricular muscles and the superior auricular muscles. Here it is less aponeurotic, and is continued over the temporal fascia to the zygomatic arch as a layer of laminated areolar tissue. It is closely connected to the integument by the firm, dense, fibro-fatty layer which forms the superficial fascia of the scalp. It is attached to the pericranium by loose cell ...

Temporal Branches Of The Facial Nerve
The temporal branches of the facial nerve (frontal branch of the facial nerve) crosses the zygomatic arch to the temporal region, supplying the auriculares anterior and superior, and joining with the zygomaticotemporal branch of the maxillary nerve, and with the auriculotemporal branch of the mandibular nerve. The more anterior branches supply the frontalis, the orbicularis oculi, and corrugator supercilii, and join the supraorbital and lacrimal branches of the ophthalmic. The temporal branch acts as the efferent limb of the corneal reflex The corneal reflex, also known as the blink reflex or eyelid reflex, is an involuntary blinking of the eyelids elicited by stimulation of the cornea (such as by touching or by a foreign body), though it could result from any peripheral stimulus. ....

Muscle
Skeletal muscles (commonly referred to as muscles) are Organ (biology), organs of the vertebrate muscular system and typically are attached by tendons to bones of a skeleton. The muscle cells of skeletal muscles are much longer than in the other types of muscle tissue, and are often known as Skeletal muscle#Skeletal muscle cells, muscle fibers. The muscle tissue of a skeletal muscle is striated muscle tissue, striated – having a striped appearance due to the arrangement of the sarcomeres. Skeletal muscles are voluntary muscles under the control of the somatic nervous system. The other types of muscle are cardiac muscle which is also striated and smooth muscle which is non-striated; both of these types of muscle tissue are classified as involuntary, or, under the control of the autonomic nervous system. A skeletal muscle contains multiple muscle fascicle, fascicles – bundles of muscle fibers. Each individual fiber, and each muscle is surrounded by a type of connective tissue ...

Head
A head is the part of an organism which usually includes the ears, brain, forehead, cheeks, chin, eyes, nose, and mouth, each of which aid in various sensory functions such as sight, hearing, smell, and taste. Some very simple animals may not have a head, but many bilaterally symmetric forms do, regardless of size. Heads develop in animals by an evolutionary trend known as cephalization. In bilaterally symmetrical animals, nervous tissue concentrate at the anterior region, forming structures responsible for information processing. Through biological evolution, sense organs and feeding structures also concentrate into the anterior region; these collectively form the head. Human head The human head is an anatomical unit that consists of the skull, hyoid bone and cervical vertebrae. The term "skull" collectively denotes the mandible (lower jaw bone) and the cranium (upper portion of the skull that houses the brain). Sculptures of human heads are generally based on ...

Superior Auricular Muscle
The superior auricular muscle is a muscle above the auricle of the outer ear. It originates from the epicranial aponeurosis, and inserts into the upper part of the medial surface of the auricle. It draws the auricle upwards. Structure The superior auricular muscle originates from the epicranial aponeurosis. Its fibres converge to be inserted by a thin, flattened tendon into the upper part of the medial surface of the auricle of the outer ear. It is the largest of the three auriculares muscles. It is thin and fan-shaped. Nerve supply The superior auricular muscle is supplied by the temporal branch of the facial nerve (VII). Additional images File:Auricularis superior.png, Auricula in context. Superior auricular shown in red.

Occipitofrontalis Muscle
The occipitofrontalis muscle (epicranius muscle) is a muscle which covers parts of the skull. It consists of two parts or bellies: the occipital belly, near the occipital bone, and the frontal belly, near the frontal bone. It is supplied by the supraorbital artery, the supratrochlear artery, and the occipital artery. It is innervated by the facial nerve. In humans, the occipitofrontalis helps to create facial expressions. Structure The occipitofrontalis muscle consists of two parts or bellies: * the occipital belly, near the occipital bone. It originates on the lateral two-thirds of the highest nuchal line, and on the mastoid process of the temporal bone. It inserts into the epicranial aponeurosis. * the frontal belly, near the frontal bone. It originates from an intermediate tendon that connects to the occipital belly. It inserts in the fascia of the facial muscles and in the skin above the eyes and nose. Some sources consider the occipital and frontal belli ...

Reconstructive Surgery
Reconstructive surgery is surgery performed to restore normal appearance and function to body parts malformed by a disease or medical condition. Description Reconstructive surgery is a term with training, clinical, and reimbursement implications. It has historically been referred to as synonymous with plastic surgery. In regard to training, Plastic Surgery is a recognized medical specialty and a surgeon can be a "board-certified" plastic surgeon by the American Board of Plastic Surgery. However, reconstructive surgery is not a specialty and there are no board-certified reconstructive surgeons. More accurately, reconstructive surgery should be contrasted with cosmetic surgery. Reconstructive surgery is performed to # Improve/restore to normal function. # Restore to a normal appearance of "abnormal" or "malformed" body parts caused by the disease or condition and/or # Improve the patient's quality of life. Separately, the patient must be healthy enough so that the benefits ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otorhinolaryngology
Otorhinolaryngology ( , abbreviated ORL and also known as otolaryngology, otolaryngology–head and neck surgery (ORL–H&N or OHNS), or ear, nose, and throat (ENT)) is a surgical subspeciality within medicine that deals with the surgical and medical management of conditions of the head and neck. Doctors who specialize in this area are called otorhinolaryngologists, otolaryngologists, head and neck surgeons, or ENT surgeons or physicians. Patients seek treatment from an otorhinolaryngologist for diseases of the ear, nose, throat, base of the skull, head, and neck. These commonly include functional diseases that affect the senses and activities of eating, drinking, speaking, breathing, swallowing, and hearing. In addition, ENT surgery encompasses the surgical management of cancers and benign tumors and reconstruction of the head and neck as well as plastic surgery of the face and neck.
