The Muscles of the Hand - Thenar - Hypothenar - TeachMeAnatomyThenar Eminence Overview Thenar eminence refers to the lump that can be seen at the base of your thumb. It is composed of three separate muscles that work to control the thin movements of the thumb. We will take a closer look at the Thenar eminence, its function and conditions that can affect it. Opponens chicks Opponens chickicis is the largest of the muscles found in the eminence of the Thenars. Its function is very important for what makes human thumbs oposable. Opponens polyciicis work to remove the thumb from the other fingers from the hand. During this movement, the thumb turns to oppose or face the other four fingers of the hand. This movement is very important for tasks such as grasping and grabbing objects. Abductor chickicis brevis The abductor chickicis brevis is found on the oponens polyicis along the outside of the thumb. Its function is to help remove the thumb from the index finger. This movement can be illustrated if the hand is placed flat on a surface and the thumb is removed from the hand. Flexible pollutants brevis The flexor chickicis brevis is also found on the polyici opponens but is inside the thumb. It is responsible for folding the thumb towards the pink finger. This movement can be demonstrated by folding the first joint of the thumb. When this happens, the thumb must be folded to point to the pink finger. Click on the thumb muscles to see the oponens chicks, abductor chickicis brevis, and flexor chickicis brevis. The medium nerve supplies nerves to the three muscles of the thorax eminence. This medium nerve comes from a group of nerves called the brachial plexus. The middle nerve runs through the inside of the arm where it eventually crosses over the elbow, providing nerves to the muscles of the forearm, wrist and hand. A small part of the flexor poleici brevis, referred to as the deep head, is supplied with nerves by the ulnar nerve. In addition, the oponens poliicis are supplied with nerves by the nerve to kill around the people. As the middle nerve, the ulnar nerve originates from the brachial plexus. It moves through the arm, crosses the elbow along the inner aspect and then moves inside the forearm. It also gives nerves to parts of the forearm, wrist and hand. The scientist John Napier once, "The hand without a thumb is in the worst nothing more than an animated spatula and in the best a pair of forceps whose points are not found correctly." In fact, the thumb is very important for the ways we interact with objects in the environment. Thenar eminence helps control the thin movements of the thumb, including being able to grab, grab and pinch objects. The abductor brevis pollicis and the flexor chickicis brevis allow the movement of the thumb towards the other fingers of the hand. Opponens chicks allow the thumb to be opposable. These movements allow us to handle and manipulate carefully objects and objects. There are several conditions that can affect the eminence of the Thenars, which leads to a decrease in the function or even . You may be experiencing a problem with thenar eminence muscles if you note: Some examples of conditions that can affect the eminence of the rigids are: Try the exercises below to maintain the eminence of the Thenars. If you are not sure about any of these exercises or have recently been injured or have had surgery on your forearm, wrist or hand, talk first to your doctor. Tumb flex and extension Raise your hand, making sure your thumb is placed away from your fingers. Move your thumb through your palm so you're playing right under your pink finger. Hold each position for 10 to 15 seconds, performing 10 repetitions with each hand. Width extension with rubber bandWatch your flat hand on a table or other hard surface. Place a rubber band around your hand to sit at the base of your finger joints. Gently move your thumb away from your other fingers in what you can go. Keep this position for 30 to 60 seconds and then release. Repeat 10 to 15 times with each hand. Hand grip exercise Pick up a tennis ball or similar in a hand. Press the ball as hard as you can for 3 to 5 seconds before slowly relaxing your grip. Repeat this 10 to 15 times in the same hand and then with the other hand. Itching force exercise Pick up a soft foam ball between the thumb and the index finger. Press the ball, keeping the position between 30 and 60 seconds. Put the pressure down. Repeat 10 to 15 times with the same hand and again with the other hand. Tomb to the list Keep your hand in front of you. Touch your thumb gently towards each of your other four fingers, keeping each position for 30 to 60 seconds. Repeat at least 4 times for each of your hands. Thenar eminence is a group of three small muscles at the base of the thumb. Despite their small size, they are very important to control the movements of the fine thumb, such as grip and pinch. Thenar eminence can be affected by a variety of conditions that can lead to a decrease in the range of movement or muscle function. If you think you are experiencing consistent symptoms with one of these conditions, make an appointment to see your doctor. Last medical review on May 28, 2019Read this following
