Anatomical Chart The Muscular System (Laminated)

Product Information

The longus colli, also called the longus cervicis, is a long muscle that spans the entire length of the cervical spine and the upper vertebrae of the thoracic spine. It is divided into three parts: Keeping the skeletal muscles healthy is important for daily functioning. This may be particularly important for older adults.

A muscle lying on the lateral side of the forearm. This muscle connects the humerus to the radius at the styloid process. It flexes the forearm. Also depending on the position of your hand, it can rotate the forearm in either direction. Coracobrachialis Deep vein thrombosis (DVT). DVT occurs when a blood clot forms in a vein. It most often happens in the thigh or lower leg. This muscle is divided into three named parts: serratus anterior superior, serratus anterior intermediate, serratus anterior inferior and runs from the front of the chest around the side to the scapula. The anterior serratus pulls the scapula outward which lifts the shoulder. It keeps the scapula in position close to the chest wall, abducts the scapula, and turns it upward to raise the point of the shoulder. If the scapula is fixed, the serratus anterior can elevate the ribs. The serratus anterior is controlled by the long thoracic nerve. Serratus means “saw-shaped” and describes this muscle’s jagged shape. Sternocleidomastoid Mild to moderate calf strains can be treated at home with rest, ice, and anti-inflammatory medications. More severe strains may need medical treatment. Achilles tendinitis

To abduct a limb or to move it away from the midline. Lifting the arms sidewards from resting position is an example of abduction. Extension Each chart groups the muscles of that region into its component groups, making your revision a million times easier. For example, upper limb muscles are grouped by shoulder and arm, forearm and hand. Next to each muscle, you’ll find its origin(s), insertion(s), innervation(s) and function(s). Muscle origins and insertions For example, if you’re performing a set of 10 repetitions, by the tenth repetition, you should be unable or nearly unable to perform another repetition. You should rarely have more than “two reps in the tank” by the end of a set if your goal is building muscle. The muscle bellies both travel towards the hyoid bone and connect via the intermediate tendon, a fibrous tissue sling that is anchored to the superior aspect of the body of hyoid bone.

An assessment of muscle strength is typically performed as part of a patient's objective assessment and is an important component of the physical exam that can reveal information about neurologic deficits. It is used to evaluate weakness and can be effective in differentiating true weakness from imbalance or poor endurance. It may be referred to as motor testing, muscle strength grading, manual muscle testing, or any other synonyms. Muscle strength can be assessed by a number of methods-manually, functionally, or mechanically. [1]Strength depends on the combination of morphological and neural factors including muscle cross-sectional area and architecture, musculotendinous stiffness, motor unit recruitment, rate coding, motor unit synchronization, and neuromuscular inhibition [2]Found only in the heart, cardiac muscle is responsible for pumping blood throughout the body. Cardiac muscle tissue cannot be controlled consciously, so it is an involuntary muscle. While hormones and signals from the brain adjust the rate of contraction, cardiac muscle stimulates itself to contract. The natural pacemaker of the heart is made of cardiac muscle tissue that stimulates other cardiac muscle cells to contract. Because of its self-stimulation, cardiac muscle is considered to be autorhythmic or intrinsically controlled. This article will introduce the muscles in each group and touch on their origin, in
