Plate 13: The Muscles of the Arm

Fig. 1. a, the biceps, (biceps flexor cubiti) arise by two portions from the scapula; they form a thick mass of flesh in the middle of the arm, which is finally inserted into the upper end of the radius; b, the brachiaeus internus, arises from the middle of the os humeri, and is inserted into […]

Plate 14: The Muscles that Raise the Eye-lids, and Sphincter or Circular Muscles

Fig. 1. A front view of this muscle, named levator palpebræ superioris: Fig. 2. a profile of the same in its natural position. This muscle arises within the orbit, and is inserted by a broad tendon into the upper eye-lid. Its name is expressive of its use. Fig. 3. Exhibits examples of sphincter muscles: a, […]

Plate 15: The Digastric Muscle

Fig. 1 and 2. The digastric muscle has its origin, a, at the lower part of the temporal bone; it runs downwards and forwards, and forms a strong, round tendon, b, which passes through a perforation in the stylo-hyoideus muscle, f; it is then fixed by a strong ligament, c, to the os hyoides, d; […]

Plate 16: The Tendons of the Toes

Fig. 1. a, the tendon of the long flexor of the toes, which divides about the middle of the foot into four portions, passing through the slits in, b, the short flexor tendons. Fig. 2. explains a similar contrivance belonging to each finger: a, a tendon of the flexor sublimus; b, a tendon of the […]

Plate 17: The Heart

Fig. 1. A section of the human heart; a, a, the superior and inferior vena cava, the veins which convey the blood to the, b, right auricle; and thence into, c, the corresponding ventricle; from this ventricle the blood is impelled through, e, the pulmonary artery, into the lungs; and returning by f, f, the […]

In the various orders of animated beings it differs, being adapted to the food on which they are accustomed to subsist. The food, […]

Plate 19: The Lacteals, and Thoracic Duct

The figure in this plate represents the course of the food, from its entrance at the mouth to its assimilation with the blood; a, the œsophagus, extending from the pharynx to, b, the stomach; where the alimentary matter, having undergone the digestive process, is converted into chyme, a soft, homogeneous substance, and escapes at c, […]

Plate 20: The Parotid Gland

Fig. 1. A dissection to exhibit the parotid gland. Fig. 2. Explains the former; a, a, the integuments turned back; h, the parotid gland; c, its pipe or duct passing over the masseter, then perforating, d, the buccinator muscle, and opening into the mouth opposite the second molar tooth. The flow of saliva into the […]

Plate 21: The Larynx

Fig. 1. The larynx, pharynx, &c. a, the os hyoides, b, the epiglottis pressed down, thus covering the glottis, or opening of the larynx; as it does in the act of deglutition. Fig. 2. Exhibits the larynx, and trachea; which is a continuation of the former; b, the epiglottis; g, the arytenoid cartilages; e, the […]
