In most mammals, the visible ear is a flap of tissue that is also called the pinna or the auricle. Vertebrates have a pair of ears, placed somewhat symmetrically on opposite sides of the head. This arrangement aids in the ability to localise sound sources.

There are three components to the ear: the outer ear, the middle ear and the inner ear. All three are involved in hearing but only the inner ear is responsible for balance. In most mammals, the visible ear is a flap of tissue that is also called the pinna or the auricle.

Diagram Of Human Anatomy Mediastinum Left View Illustration Large Image

Nerves: details the nervous anatomy of the mediastinum including notably the route of the phrenic and vagus nerves as well as the anatomy of the sympathetic trunk at the thoracic level. Heart: the external morphology of the heart in the mediastinum and the various chambers of the heart on the anatomical sections are detailed on these diagrams.

The superior mediastinum contains three visceral organs including the esophagus, the trachea and remnants of the thymus. The nerves that run through this area are three and there are also two different nervous plexuses.

Middle Inferior Mediastinum. The middle inferior mediastinum contains a single nerve which is the phrenic nerve, the heart and the pericardium. The vessels present include: the ascending aorta. the pulmonary trunk. the superior vena cava. the pericardiacoophrenic artery.

Muscles Arm Human Anatomy Illustration Diagram En Medical Image

The human arm is divided into two main regions, the portion from the elbow to the wrist known as the forearm, and the segment from the shoulder to the elbow referred to as the arm. Arm muscle anatomy enables the arm to perform a variety of movements, including flexion, extension, pronation, and supination.

Each of these two sections of the human arm consists of arm muscle anatomy that allows for the flexion, extension, pronation, and supination of the arm, as will be further discussed below. While four muscles are responsible for the upper arm musculature, there are over twenty muscles that move the forearm, wrist, hands, and fingers.

Arm muscle anatomy enables the arm to perform a variety of movements, including flexion, extension, pronation, and supination. The forearm flexors include the biceps brachii, coracobrachialis, and brachialis muscles, which help to bend the arm at the elbow, as when flexing one’s arm to show off the muscles.
