Extraocular muscle. In pharmacology the term agonist-antagonist or mixed agonist/antagonist is used to refer to a drug which under some conditions behaves as an agonist (a substance that fully activates the receptor that it binds to) while under other conditions, behaves as an antagonist (a substance that binds to a receptor but does not activate and can block the activity of other agonists). The muscles outside an organ that control its position, such as the EM of the eye or tongue. Action: flexes distal finger joints, aids in wrist flexion. Action: elevates mandible to close jaw. Arm muscle. Nerve: long thoracic (C5-C7). 3. Origin: adjacent facial muscles that surround mouth. Contraction of this muscle prevents urination; relaxation permits it. Insertion: olecranon process. The movement of agonist/antagonist muscle groups is coordinated by the central and peripheral nervous system. Insertion: distal end of radius. Forearm muscle. … Forearm, posterior: abductor pollicis longus, anconeus, brachioradialis, extensor carpi radialis brevis, extensor carpi radialis longus, extensor carpi ulnaris, extensor digitorum, extensor digitorum minimi, extensor indicis, extensor pollicis brevis, extensor pollicis longus, and supinator muscles. Insertion: distal phalanges of toes 2-5. Insertions: contralateral arytenoid cartilage. Nerve: lateral and medial pectoral (C5-T1). Nerve: trigeminal (CN V). One of the mastication muscles. Antagonist and agonist muscles often occur in pairs, called antagonistic pairs.As one muscle contracts, the other relaxes. Insertion: distal phalanges of fingers (digits 2-5). A muscle arising on the inner surface of the thyroid cartilage. Neck and back muscle. Origin: ischial tuberosity, linea aspera and second supracondylar ridge of femur. Typically it is a mass of fleshy tissue, attached at each extremity by means of a tendon to a bone or other structure. Nerve: lumbar L1-L3. Facial muscle. 2. Origin: proximal three-fourths of ulna. n ANTAGONIST (a) * * * a muscle that counteracts the action of another muscle (the agonistic muscle). Insertion: proximal medial tibia. Insertion: greater tubercle of humerus. These cells largely generate energy via aerobic oxidation and are suited for maintaining contractions for an extended time. Insertion: orbicularis oris muscle at angle of mouth. Suboccipital: obliquus capitis and rectus capitis muscles. A muscle that on contraction draws a part away from the median plane of the body or the axial line of an extremity. Bridges occur between thick and thin filaments and in contraction the bridges pull thin filaments past the thick ones using a ratchet mechanism. Nerve: ulnar, median (C8-T1). Nerve: oculomotor (CN III). Nerve: trigeminal (CN V). Action: turns eye down and medially. Shoulder muscle. Leg muscle. Action: turns eye medially. Antagonist Muscles at Work in a Bicep Curl. Action: adducts, flexes, and medially rotates thigh. Action: compresses check against teeth, retracts angle of mouth. Nerve: deep peroneal (L5-S1). In the two cases presented above, not only were the wrist flexor muscles strengthened, which enabled elbow flexion, but also the balance between the flexors and extensors was maintained by the increased muscle strength in the, These two spinal interneuronal populations have been shown to be responsible for suppressing stretch reflex activity in, (30,31) The BF exercises are designed to increase ROM at the proximal joints through coordination of the supporting agonist and, All patients who were treated with botulinum toxin injection to the, The 1 Hz stimulation protocol of the premotor cortex ipsilateral to the lesion appeared to have a positive effect on, The findings of this study showed that a cycling exercise with HTS, utilizing electrically stimulated eccentric,  A sufficient balance between agonist and, Considering the activation pattern of the, Reduction of EBA at rest in the spastic muscles, increase of its amplitude in the, The implication of this finding is that, during in vivo exercise, appropriate coactivation and co-ordination around the joint may be maintained, despite exercise induced fatigue of an. Thigh muscle. Origin: Anterior medial surface of ribs 3-5. Insertion: iliotibial tract of fascia lata, gluteal tuberosity of femur. Nerve: tibial (S1-S2). antagonist definition: 1. a person who is strongly opposed to something or someone: 2. a muscle that performs the…. (05 Mar 2000) Lexicographical Neighbors of Antagonistic Muscles To flex the arm, the biceps contracts and the triceps relaxes; to extend the arm, the triceps contracts and the biceps relaxes. Nerve: facial (CN VII). Action: flexes big toe, plantarflexes foot. It adducts, flexes, and medially rotates the thigh and is controlled by the obturator nerve. Extraocular muscle. Action: abducts arm. Nerve: facial (CN VII). The EOM are: the inferior and superior oblique muscles, and the lateral, medial, inferior, and superior rectus muscles. Action: empties bladder. The abdominal muscles are made up of the cremaster, external abdominal oblique, iliacus, psoas major, pyramidalis, quadratus lumborum, rectus abdominis, and transversus abdominis muscles. Origin: upper edge of manubrium, middle of upper clavicle. Leg muscle. Insertion: ventral tongue, hyoid bone. See: illustration. Origin: anterior surface of lower (distal) humerus.
