The short head arises from the lateral lip of the linea aspera and lateral supracondylar line of femur. The muscle fibers from both heads converge and form the conjoint aponeurotic sheet that inserts onto the head of fibula. The levator labii superioris is innervated by the zygomatic and buccal branches of facial nerve . Its blood supply is provided by the facial artery and infraorbital branch of the maxillary artery. The orbicularis oris is innervated by the buccal and marginal mandibular branches of the facial nerve . In the posterior thigh the bulk of the musculature is made up of three long muscles that are collectively called the hamstrings.
Correctly label the following muscles involved in chewing. Correctly label the anatomical features of the femur and patella. Correctly label the anatomical features of the scapula.

The short head originates on the coracoid process of the scapula. The gastrocnemius is innervated by the anterior rami of S1 and S2 spinal nerves, carried by the tibial nerve into the posterior compartment of the leg. Both medial and lateral heads of gastrocnemius are supplied by the lateral and medial sural arteries, which are direct branches of the popliteal artery. One of the large muscles of the leg it connects to the heel.
Below the gluteus maximus is the smaller gluteus medius. The gluteus medius muscle helps abducts the thigh along with the gluteus maximus, but can rotate the thigh inward where the gluteus maximus rotates the thigh outward. The anterior fontanel can still be palpated 18 to 24 months after birth. The frontal bone and mandible are separate right and left bones at birth. The skull grows more rapidly than the rest of the skeleton during childhood.
For example, suppose a doctor was trying to describe an area of the body to another physician on a patient who is lying face down? Anatomical terms would allow this discussion to happen with ease. Usually as one muscle contracts , the opposing muscle elongates and vice versa. For example, think about when you bend your arm to bring food to your mouth. Multiple muscles on the front of your arm shorten (biceps, brachialis, etc.) to allow for this to happen.
Extensor Digitorum Longus Edl
Nervous supply of the depressor anguli oris stems from the marginal mandibular and buccal branches of facial nerve . It is vascularized by the inferior labial branch of the facial artery and the mental branch of the maxillary artery. Semitendinosus is a long, fusiform muscle that runs in the posterior thigh, medially to biceps femoris.
Through these actions, the orbicularis oris facilitates speech and helps produce various facial expressions. The orbicularis oris is a circular composite muscle that surrounds the mouth and forms the majority of lips. It consists of two parts; labial and marginal, with the border between them corresponding to the margin between the lips and the surrounding skin. Both portions originate from the modiolus, which is a fibromuscular structure found on the lateral sides of the mouth where several facial muscles converge.

In conjunction with the soleus muscle, it is a component of a composite, three-headed group of muscles referred to as triceps surae. Together, they act in many basic activities, such as walking, running and leaping. This article will outline the morphology of the gastrocnemius muscle, as well as its functional and clinical anatomy. What muscles are responsible for the motion of the leg in the above picture. What muscles are responsible for the position of the left thigh in the above picture. You’ve finished the muscle labeling quiz, now it’s time to take things to the next level with our selection of interactive leg muscles quizzes.
Correctly label the muscles of the thoracic cavity and abdomen. The action for the vastus lateralis muscle is to __________ the knee. Correctly label the following antagonistic muscles of the upper arm. Match each label to its corresponding muscle of the quadriceps femoris. The transverse part is found in the area over the dorsum of the nose. It arises superolateral to the incisive fossa, lateral to the alar part.
The muscle consists of an occipital and a frontal part, which are connected by a fibrous sheath called the epicranial aponeurosis . Both the occipital and frontal parts contain a pair of quadrangular muscle heads. The corrugator supercilii is a slender muscle found deep to the medial end of the eyebrows.
The levator labii superioris alaeque nasi is a slender, strap-like muscle found on both sides of the nose. It originates from the upper part of the frontal process of the maxilla and passes inferolaterally, inserting on the perichondrium and the skin over the major alar cartilageof the nose. Some of the fibers pass into the lateral part of the upper lip and blend with levator labii superioris and orbicularis oris.
As these muscles contract and relax, they move skeletal bones to create movement of the body. Smaller muscles help the larger muscles, stabilize joints, help rotate joints, and facilitate other fine-tuned movements. A chest muscle that pulls the arm in towards the body. This is one of the internal rotator muscles that attach the humerus and internally rotate the arm.
The auditory ossicles are named the malleus, incus, and stapes. Forensic pathologists look for a fractured hyoid as evidence of strangulation. The hyoid is one of the few bones that does not articulate with any other. There are , three auditory ossicles in each middle-ear cavity and the hyoid bone beneath the chin. Place the following terms in order moving from superficial to deep. Correctly label the following anatomical parts of the glenohumeral joint.
