The pyramidal muscle (m. Pyramidalis) is triangular in shape, located in front of the lower part of the rectus abdominis muscle. The muscle begins on the pubic symphysis.
In children of the first year of life, the pupil is narrow (about 2 mm), weakly responds to light, does not expand well. In the normal eye, the pupil value continuously changes from 2 to 8 mm under the influence of changes in illumination.
From the capillaries of the lung, the venules begin, which merge into larger veins and in each lung form two pulmonary veins. Of the two right pulmonary veins, the larger diameter has an upper diameter, since blood flows from it on two parts of the right lung (upper and middle). Of the two left pulmonary veins, the lower vein has a larger diameter.
The pulmonary trunk (truncus pulmonalis) 30 mm in diameter emerges from the right ventricle of the heart, from which it is delimited by its valve. The beginning of the pulmonary trunk and, accordingly, its opening is projected onto the anterior thoracic wall above the site of attachment of cartilage III of the left rib to the sternum.
The valve of the pulmonary artery is separated from the fibrous carcass of the heart by the muscular septum of the outlet section of the right ventricle. This valve does not have a fibrous support. Its semilunar base rests on the myocardium of the outlet part of the right ventricle.
Symptomatic pubic symphysis (symphisis pubica) connects the symphysial surfaces of two pubic bones, between which is a fibrous-cartilaginous interoblock disc (discus interpubicus).
The pubic bone (os pubis) has an enlarged part - the body, and two branches. The body of the pubic bone (corpus ossis pubis) forms the anterior section of the acetabulum.
The prostate gland (prostata, s.glandula prostatica) is an unpaired musculo-glandular organ. Iron secretes the secret that is part of the sperm. The secret liquefies the sperm, promotes sperm motility.
The pre-vertebral nerve (n. Vestibulocochlearis) is formed by sensitive nerve fibers from the organs of hearing and balance. On the ventral surface of the brain, the pre-cochlear nerve leaves behind the bridge, laterally from the facial nerve.
The posterior tibial artery (a. Tibialis posterior) serves as a continuation of the popliteal artery, passes in the shin-channel, which leaves under the medial edge of the soleus muscle.
The posterior artery of the foot (a.dorsalis pedis) is an extension of the anterior tibial artery, going anteriorly from the ankle joint between the tendons of the long extensor of the fingers in a separate fibrous canal.
The portal vein (liver) (v. Portae hepatis) occupies a special place among the veins that collect blood from the internal organs. It is not only the largest visceral vein (its length is 5-6 cm, diameter 11-18 mm), but also bringing the venous link of the so-called portal system of the liver.
The most difficult is the popliteal fossa (fossa poplitea), bounded from above by the tendons of the semitendinous and semimembranous muscles (medially) and the tendon of the biceps femoris (laterally).
The popliteal artery (a. Poplitea) is a continuation of the femoral artery. At the level of the lower edge of the popliteal muscle is divided into its terminal branches - the anterior and posterior tibial arteries.
Pleura (pleura) is a thin serous membrane enveloping each lung (visceral pleura) and lining the walls of its pleural cavity (parietal pleura).
Placenta (placenta), or a child's place, is a temporary organ that forms in the mucous membrane during pregnancy, and connects the fetal organism with the mother.
The pituitary gland (hypophysis, s.glandula pituitaria) is located in the hypophyseal fossa of the Turkish saddle of the sphenoid bone and is separated from the cranial cavity by the appendage of the hard shell of the brain, which forms the diaphragm of the saddle.
The pineal body (pineal gland, epiphysis of the brain, corpus pineale, s.glandula pinealis, s.epiphisis cerebri) refers to the epithelamus of the diencephalon and is located in a shallow furrow separating the upper mounds of the midbrain roof.
Pharynx - an unpaired organ located in the region of the head and neck, is part of the digestive and respiratory systems. It is a hollow funnel-shaped tube suspended from the outer base of the skull.
The pharyngeal (adenoid) tonsil (tonsilla pharyngeals, s.adenoidea) is unpaired, located in the region of the arch and partly the posterior pharyngeal wall, between the right and left pharyngeal pockets (Roshenmuller fossae).
