What else can I help you with?
Which bones of the body are used to go from the anatomical position to holding a handgun in front of you with both hands?
To go from the anatomical position to holding a handgun in front of you with both hands, you primarily use the bones of the arm (humerus, radius, ulna) and hand (carpal, metacarpal, phalanges). The shoulder bones (scapula, clavicle) and chest (ribs, sternum) are also involved in stabilizing and supporting the arm during this action.
What is the joint action during the concentric phase of reverse fly?
During the concentric phase of a reverse fly exercise, the shoulder joint primarily goes through horizontal abduction as the arms move outward away from the body. The scapulothoracic joint also engages to stabilize the shoulder blades and maintain proper alignment. This coordinated action involves the posterior deltoid and other muscles of the upper back to perform the movement efficiently and effectively.
List of synergist and antagonist muscles?
Some of the synergist muscles in the human body are the masseter, temporalis, supraspinatus, and the extensor digitorum. Examples if the antagonist muscles are the flexor digitorum superficial is, triceps brachii, extensor carpi radials longus, and the internal intercostals.
Which muscle was named for its action?
levator labii superioris ----------- There are actually several muscles named for their actions, levator scapuli is another. Others are named for their location, brachioradialis, or their length or shape, rhomboids, etc.
What is the difference between a compound action potential and a single action potential?
Single action potentials follow the "all or none" rule. That is, if a stimulus is strong enough to depolarize the membrane of the neuron to threshold (~55mV), then an action potential will be fired. Each stimulus that reaches threshold will produce an action potential that is equal in magnitude to every other action potential for the neuron. Compound action potentials do not exhibit this property since they are a bundle of neurons and have different magnitudes of AP's. Thus compound action potentials are graded. That is, the greater the stimulus, the greater the action potential.
What is the action of the serratus anterior?
Abducts scapula (moves scapula away from spinal column)
What is the action of the serratus anterior muscle?
Abducts scapula (moves scapula away from spinal column)
What is the action of the levitor scapulae muscle?
Raises the scapula at the Scapulothoracic Joint or inclines neck to corresponding side if the scapula is fixed
What is the prime mover of shoulder abduction?
The prime muscle differs depending on the degree of abduction. From 1 to 20 degrees it is the supraspinatus muscle, from 20 to 90 degrees it is the deltoid and from 90 degree and above the action is done by that rotate the scapula (trapezius and serratus anterior).
What is the antagonist of the anterior deltoid muscle?
The antagonist of teres minor is: To medial rotation: latissimus dorsi, long head of triceps, pectoralis major, subscapularis. In Extension of humerus: latissimus dorsi, posterior deltoid and long head of triceps
What is your recommended treatment for AV malformation of the right posterior parietal region?
Treatment for an arteriovenous malformation (AVM) in the right posterior parietal region typically involves embolization, surgery, or stereotactic radiosurgery. The choice of treatment depends on the size, location, and symptoms caused by the AVM. It is important to consult with a neurosurgeon or neurointerventionalist to determine the best course of action.
What muscles involved in arm flexion?
arm flextion : Muscle Origin Insertion Action Coracobracialis Corocoid process of scapula Middle of medial shaft of humerus Flexes and adducts the humerus Biceps Brachii Short head- Coracoid process of scapula Long head- Supraglenoid tubercle of scapula Tuberosity of the radius and aponeurosis of biceps brachii Flexes elbow, supinates forearm, flexes shoulder joint Triceps Brachii Long head- Infraglenoid tubercle of scapula Lateral head- Posterior surface of proximal half of humerus Medial head- Posterior surface of distal half of humerus All heads- olecranon process of ulna Long head- Extends and adducts the shoulder All heads- Extend the forearm (elbow) Subclavius First rib and cartilage Inferior, lateral aspect of clavicle Elevates first rib, stabilizes sternoclavicular joint, draws clavicle down
What is the intended action of the trapezius in a barbell shrug?
Elevation, depression, and retraction of scapula. Upper is also involved in extension of the head.
What action do tibialis anterior and posterior act as synergists?
It involves the medial cuneiform and 1st metatarsal of the ankle.
What is action of water?
The action of running water is actually quite similar to the action of any running liquid. It moves from one location down to another location.
What is action of running water?
The action of running water is actually quite similar to the action of any running liquid. It moves from one location down to another location.
How does the supraspinatus muscle lift the arm?
The supraspinatus muscle, part of the rotator cuff, initiates arm abduction by stabilizing the shoulder joint and helping to lift the arm away from the body. It contracts to pull the humeral head into the glenoid cavity, allowing the arm to move upward. This action is crucial in the first 15 degrees of abduction, after which other muscles, primarily the deltoid, take over to continue lifting the arm.
