Extrinsic muscles Extrinsic muscles. Definition. noun. A group of muscles lying superficially on a structure, in contrast to intrinsic muscles, which are located deeply. Supplement.For instance, the extrinsic muscles of the tongue include genioglossus muscle, hyoglossus muscle, styloglossus muscle, and palatoglossus muscle.Since they are extrinsic muscles, they are located on the surface of the tongue, and attach the tongue to other structures.xtrinsic muscles.

- Both your feet and your hands have extrinsic and intrinsic muscles. Extrinsic muscles originate far away from the joints that they move. For the foot, there are toe muscles that start on the shin bones and turn into tendons that attach on the ends of the toes.he intrinsic muscles are like the “core” muscles of the foot. Because they are deep and don’t cross over too many joints, they can work well in stabilizing and protecting the arch and structures within the foot. If the foot intrinsic muscles are weak, the foot structures are more prone to increased stress and injury.

Motivation Intrinsic and Extrinsic Motivation A motivation may be intrinsic, extrinsic, or both. Intrinsic motivation is the motivation to act for the sake of the activity alone. For example, people have intrinsic motivation to write poetry if they do it simply because they enjoy it. Extrinsic motivation, on the other hand, is the motivation to act for external rewards. For example, people have extrinsic motivation to write if they do so in the hopes of getting published, being famous, or making money. Incentives An incentive is an environmental stimulus that pulls people to act in a particular way.

- Simultaneously, the intrinsic muscles of the eye serve to focus the eye and control the amount of light entering it. Each eye is held in place by three pairs of taut, elastic muscles (extrinsic muscles) that constantly balance the pull of the others.The superior rectus acts to roll the eyeball back and up, but it is opposed by the inferior rectus.he eye muscle is the fastest reacting muscle of the whole body, contracting in less than 1/100th of a second. In fact, the eye muscles work together to carry out no less than seven coordinated movements and allow the eye to track many different kinds of moving object.

Intrinsically or extrinsically motivated?? Rating Newest Oldest. Best Answer: If you are intrinsically motivated, you are self-motivated. If you are extrinsically motivated, you are motivated by a reward/punishement outside of yourself. For instance, wanting to be able to be proud of your work is intrinsic motivation. Wanting to get the prize offered for the best work is extrinsic motivation. Obviously, in real life situations these often are blended together. I am motivated by both, depending on the situation.

Pulmonary Capillary Wedge Pressure What does it measure? Pulmonary capillary wedge pressure (PCWP) provides an indirect estimate of left atrial pressure (LAP). Although left ventricular pressure can be directly measured by placing a catheter within the left ventricle, it is not feasible to advance this catheter back into the left atrium.

Intrinsic Hand Deformity Anatomy of the muscles of the hand. Normal positioning and movement of the digits depends on the functional integrity of extrinsic and intrinsic muscles. The extrinsic muscles originate in the forearm, and the intrinsic muscles originate distal to the wrist.he intrinsic muscles are volar to the axis of rotation of the MCP joint and dorsal to the axis of the PIP joint. MCP joint hyperextension tightens the intrinsics. Results of this test are compared with those in the contralateral, normal hand.

Hand â Bones, Ligaments, Muscles & Conditions Intrinsic muscles only act on the fingers. The extrinsic muscles are the long flexors and extensors, which run from the forearm into the hand, providing strength to the hand and wrist. The flexors enable the fingers to bend while the extensor muscles are used to straighten the fingers.
