Upper Limb | Introduction | Hand and Wrist Bones | Anatomy for Medical Students

The upper limb is divided into regions. So far, we have covered a number of lectures on upper limb anatomy that you can easily access here at sqadia.com. The topic of discussion in the lecture is the Hand and Wrist. A number of complex joints make up the hand, which is at the extremity of the upper limb and is used for manipulating, gripping, and grasping. These actions are made possible by the thumb's opposing motion. In this anatomy video, we will go through the details of the intrinsic muscles of the hand. We will also talk about 🟡 Wrist 🟡 Superficial and Deep Fascia of the Hand 🟡 Intrinsic Muscles of the Hand ▬ 🕘 TIMESTAMPS ▬▬▬▬▬▬▬▬▬▬ 0:00 - Upper Limb, Hand and Wrist Bones Anatomy 0:32 - Pincer-Like grip 1:03 - Wrist bones anatomy 2:14 - Metacarpals 2:22 - Phalanges 2:42 - Muscles of the hand 3:37 - Compartments of the hand 4:40 - Link to Upper Limb, Hand and Wrist anatomy on sqadia.com ▬ 📃 Upper Limb: Hand and Wrist ▬▬▬▬▬▬▬▬▬▬ A total of 27 bones make up the hand anatomy and wrist joint. These bones may roll, slide, and rotate to explore and control the surroundings and things. The hand is regarded as the most dexterous portion of the body because of this. The palmar or volar surface of the hand is located on its anterior side. The dorsal surface is the posterior aspect. The thumb (Pollux) is digit one for identifying the individual digits, with the other numerals coming in order from lateral to medial. The Muscles of the hand are divided into extrinsic and Intrinsic muscles of the hand. ▬ 📜 Wrist and Fascia ▬▬▬▬▬▬▬▬▬▬ The Wrist is made up of Carpal Bones. They are an essential part of the hand anatomy. The carpal bones are arranged in: 👉 Proximal Row These four bones are - The Pisiform, Triquetrum, Lunate, and Scaphoid. 👉 Distal Row These four bones are - The Hamate, Capitate, Trapezoid, and Trapezium on the lower side of the hand. The stability of the wrist is dependent on ligaments. Just along the distal row of the carpal bones, we have the part of the hand known as the metacarpus. 👉 Five metacarpals They are named from the lateral side, the thumb being the metacarpal 1 and then moving medially to the index, middle, ring, and little finger. These five bones make joints with the carpal bones known as the Metacarpophalangeal joints. The hand anatomy is divided up into 11 compartments: 🔵 Four dorsal interossei compartment 🔵 Three volar interossei compartment 🔵 Adductor compartment 🔵 Thenar compartment 🔵 Hypothenar compartment 🔵 Central compartment The fascia of the hand is divided into Superficial and Deep Fascia. 👉 Superficial Fascia It mainly comprises a muscle known as the Palmaris Brevis. 👉 Deep Fascia Structures like the flexor retinaculum, palmer aponeurosis, and flexor sheaths of the fingers are part of the Deep fascia of the hand. All three structures are explained in great detail in the lecture. You can learn about the relations of structures to the flexor retinaculum with the help of mnemonic so do watch the full video. ▬ 📃 Intrinsic Muscles of the Hand ▬▬▬▬▬▬▬▬▬▬ The muscles that originate and insert into the anatomical structure of the hand are called the intrinsic muscles. On the other hand, the muscles that originate from the forearm or the arm but insert into the anatomical structures of the hand are called the extrinsic muscles. In this video we have discussed the intrinsic muscles of hand anatomy only, the extrinsic muscles have already been discussed in our lecture “Upper Limb: Forearm” The intrinsic muscles of the hand are enlisted here: 🔴 Thenar muscles 🔴 Hypothenar muscles 🔴 Lumbrical muscles. 🔴 Palmer and Dorsal interossei 🔴 Palmaris brevis 🔴 Adductor pollicis The origin, insertion, and action of these muscles are discussed in the third section of our lecture. Watch it to learn about these muscles in detail. ▬ 🎬 5500+ sqadia.com Medical Videos ▬▬▬▬▬▬▬▬▬▬ 👩🏻‍⚕️ Accessible Medical Student Education 24/7/365 💡 Simplifying Medical Learning 💪 Study Hard, Dream Big, Achieve More #upperlimbanatomy #anatomyvideos #anatomy #anatomynotes #humananatomymadesimple #skeletalsystem #medicalvideo #medicallectures #medicalstudy #medicalstudents
