The human hand is a complex network of bones, muscles, nerves, tendons, ligaments and blood vessels. There are 34 muscles in each hand, which are categorised into groups such as thenar muscles, which control the thumb, and hypothenar muscles, which line the outer edges of the palm on the outside of the pinkie finger. These muscles work together to help us move our hands and fingers.

There are 34 muscles in each hand
Yes, your hands do have muscles. In fact, there are 34 muscles in each hand. These muscles are categorised into groups, including thenar muscles, which control your thumb, and hypothenar muscles, which line the outer edges of your palm on the outside of your pinkie finger.
Healthcare providers categorise the muscles in your hand into groups. Thenar muscles are those that control your thumb, and you can feel them bulge at the base of your thumb in the palm of your hand. Hypothenar muscles, meanwhile, line the outer edges of your palm on the outside of your pinkie finger.
The muscles in your hand are what allow you to move your hand and fingers. They contract, allowing movement of the bones in your hand. The tendons in your hand connect muscles to the bone, allowing movement. The palmar interossei pull your fingers together, while the dorsal interossei allow you to spread your fingers away from each other.

Muscles contract to allow movement of the bones in the hand
The human hand is a complicated network of bones, muscles, nerves, tendons, ligaments, connective tissue and blood vessels. There are 34 muscles in each hand, which can be categorised into groups such as thenar muscles, which control the thumb, and hypothenar muscles, which line the outer edges of the palm on the outside of the pinkie finger. Muscles are groups of cells that can contract and relax, allowing movement of the bones in the hand. The tendons connect muscles in the arm or hand to the bone to allow movement. For example, the interossei muscles allow us to spread our fingers away from each other, while the palmar interossei pull our fingers together.

Interossei muscles allow us to spread our fingers apart and pull them together
Our hands are a complicated network of bones, muscles, nerves, tendons, ligaments, connective tissue and blood vessels. There are 34 muscles in each hand, which are categorised into groups by healthcare providers.
The interossei muscles begin between the bones of the hand. There are four dorsal and three palmar interossei muscles. While all interossei bend the MCP joints, the dorsal interossei allow us to spread our fingers away from each other. The palmar interossei pull our fingers together. The first dorsal interosseous muscle is the largest and originates from the first and second hand bones.

Thenar muscles control the thumb
There are 34 muscles in each of your hands. The thenar muscles are a group of muscles that control the thumb. You can feel them bulge at the base of your thumb in the palm of your hand.
The thenar muscles are part of a complicated network of bones, muscles, nerves, tendons, ligaments, connective tissue and blood vessels that make up the hand and wrist. The muscles are the structures that can contract, allowing movement of the bones in the hand. The thenar muscles are distinct from the hypothenar muscles, which line the outer edges of the palm on the outside of the pinkie finger.
The interossei muscles begin between the bones of the hand. There are four dorsal and three palmar interossei muscles. While all interossei bend the MCP joints, the dorsal interossei allow us to spread our fingers away from each other. The palmar interossei pull our fingers together. The first dorsal interosseous muscle is the largest and originates from the 1st and 2nd hand bones.
