La arteria braquial se bifurca en las arterias radial y cubital. La arteria radial se encuentra en el antebrazo y se extiende hacia la mano, mientras que la arteria cubital se encuentra en el brazo y también se extiende hacia el antebrazo y la mano. Por lo tanto, la respuesta correcta es "A y C", ya que ambas opciones mencionan las arterias en las que se bifurca la arteria braquial.

The correct answer is Nervio Axilar. The question is asking which nerve innervates the deltoid muscle. The deltoid muscle is located in the shoulder and is responsible for abducting the arm. The nerve that innervates the deltoid muscle is the axillary nerve, which arises from the brachial plexus and provides motor innervation to the deltoid muscle.

The correct answer is Nervio Axilar, Arteria Circunfleja humeral posterior. The question is asking which artery and nerve pass through the posterior surgical neck of the humerus. The Nervio Axilar (Axillary Nerve) and Arteria Circunfleja humeral posterior (Posterior Circumflex Humeral Artery) both pass through this area.

Todos los músculos mencionados en la pregunta son músculos de la eminencia tenar. La eminencia tenar es una prominencia muscular en la base del pulgar, y estos músculos son responsables de los movimientos y la función de la mano y el pulgar. El oponente del pulgar es responsable de oponer el pulgar a los otros dedos, el flexor corto del pulgar flexiona el pulgar y el abductor corto del pulgar abduce el pulgar. Por lo tanto, la respuesta correcta es "Todos".

The correct answer is "Todas" (All). This means that all of the listed elements are principal components of the elbow joint. The elbow joint consists of various structures that work together to enable movement and provide stability. These structures include the synovial membrane, hyaline cartilage, fibrous membrane of the capsule, and fatty pads. Each of these components plays a crucial role in the functioning of the elbow joint.

The correct answer is Arteria Radial. The anatomical snuffbox is a triangular depression on the dorsum of the hand, and the radial artery passes through it. The radial artery is one of the major arteries in the forearm and supplies blood to the hand and fingers. It is commonly used for measuring the pulse and for arterial blood gas sampling.

The correct answer is "Todas" (All). This means that all of the ligaments mentioned in the options are ligaments of the sternoclavicular joint. The ligaments include the anterior sternoclavicular ligament, the interclavicular ligament, the costoclavicular ligament, and the posterior sternoclavicular ligament.

The correct answer is "Sub-escapular". The subscapularis muscle is the muscle that inserts into the lesser tubercle of the humerus. It is one of the four muscles that make up the rotator cuff in the shoulder joint. Its main function is to internally rotate the arm and stabilize the shoulder joint.

La articulación esterno-clavicular es del tipo sinovial y en silla de montar. Este tipo de articulación permite el movimiento en múltiples direcciones, incluyendo flexión, extensión, abducción, aducción, rotación y circunducción. La presencia de una superficie cóncava y otra convexa encajadas entre sí, como en una silla de montar, permite este amplio rango de movimiento. La presencia de una cápsula articular y líquido sinovial también indica que se trata de una articulación sinovial.

The correct answer is Sinovial- En hueco y bola. This means that the type of joint that the glenohumeral joint is classified as is a synovial joint. This type of joint allows for free movement and is characterized by the presence of a synovial cavity, which is a space filled with synovial fluid. The glenohumeral joint is a ball-and-socket joint, which means that it allows for movement in multiple directions, similar to a ball fitting into a socket.

En la fosa del codo se encuentran el tendón del músculo Bíceps Braquial, la arteria Braquial y el nervio Mediano. Por lo tanto, todas las opciones mencionadas son correctas.

The correct answer is "Sinovial." The acromioclavicular joint is a synovial joint, which means it is a freely movable joint. It is a plane joint that allows gliding movements between the acromion process of the scapula and the clavicle. This type of joint is surrounded by a synovial capsule and contains synovial fluid, which helps to reduce friction and facilitate smooth movement between the bones.

The correct answer is Arteria Braquial. The question asks for the artery of the anterior compartment of the arm, and the Arteria Braquial is the correct answer. The Arteria Braquial is a major artery that runs along the anterior aspect of the arm and is responsible for supplying blood to the muscles and tissues of the anterior compartment of the arm. The Arteria Radial, on the other hand, is a different artery that supplies blood to the lateral aspect of the forearm. Therefore, the correct answer is Arteria Braquial.

The correct answer is "Nervio Radial y Musculo- cutaneo". The explanation for this answer is that the innervation of the elbow primarily comes from the Radial nerve and the Musculo-cutaneous nerve. These nerves supply motor and sensory innervation to the muscles and skin around the elbow joint. The Radial nerve innervates the extensor muscles of the forearm, while the Musculo-cutaneous nerve innervates the biceps brachii muscle. Therefore, both nerves play a significant role in the innervation of the elbow.

Las articulaciones interfalángicas son del tipo bisagra. Este tipo de articulación permite el movimiento de flexión y extensión en una sola dirección, similar a una bisagra de una puerta. En el caso de las articulaciones interfalángicas, permiten el movimiento de flexión y extensión de los dedos. Por lo tanto, la respuesta correcta es "Bisagra".
