The sphenoid sinus (sinus sphenoidalis) is located in the body of the sphenoid bone. The lower wall of the sinus participates in the formation of the wall of the nasal cavity. The cavernous sinus is adjacent to the upper part of the lateral wall.
The occipital bone (os occipitale) is located in the posterior lower part of the cranial section of the skull. This bone is divided into the basilar part, two lateral parts and the occipital squama, which surround the large (occipital) opening (foramen magnum).
The lens, located behind the chambers of the eyeball, has the shape of a biconvex lens with high light-refracting power. The anterior surface of the lens (facies anterior lentis) and its most protruding point - the anterior pole (polus anterior) are directed towards the posterior chamber of the eyeball.
The sacrum (os sacrum) consists of five sacral vertebrae (vertebrae sacrales), which fuse into one bone in adolescence. The sacrum is triangular in shape. It is a massive bone, as it bears the weight of almost the entire body.
Cranial nerves are nerves that exit or enter the brain stem. Humans have 12 pairs of cranial nerves (nervi craniales). They are designated by Roman numerals according to the order in which they are located.
The vomer is an unpaired bone plate that participates in the formation of the bony nasal septum. The lower edge of the vomer fuses with the nasal ridges of the maxilla and palatine bone.
The cornea is one of the transparent media of the eye and is devoid of blood vessels. It has the appearance of a watch glass, convex in front and concave in the back. The diameter of the cornea is 12 mm, the thickness is about 1 mm.
Connective tissue (textus connectivus) is a large group of tissues, including connective tissues proper (loose and dense fibrous tissues), tissues with special properties (reticular, fatty), liquid (blood) and skeletal (bone and cartilage).
The conjunctiva (tunica conjunctiva) is a pale pink connective tissue membrane. It is divided into the conjunctiva of the eyelids (tunica conjunctiva palpebrarum), which covers the inside of the eyelids, and the conjunctiva of the eyeball (tunica conjunctiva bulbaris), which is represented on the cornea by a thin epithelial covering.
In the nervous system, nerve cells do not lie in isolation. They come into contact with each other, forming chains of neurons - impulse conductors. The long process of one neuron - neurite (axon) comes into contact with short processes (dendrites) or the body of another neuron, the next in the chain.
The common iliac artery (a. iliaca communis) is paired and is formed by the division (bifurcation) of the abdominal part of the aorta; its length is 5-7 cm, diameter is 11.0-12.5 mm. The arteries diverge to the sides, go downwards and outwards at an angle that is greater in women than in men.
The coccyx (os caccygis) is the result of the fusion of 3-5 rudimentary coccygeal vertebrae (vertebrae coccygeae). The coccyx has the shape of a triangle, slightly curved forward.
The coccygeal plexus (plexus coccygeus) is formed by the fibers of the anterior branches of the fourth and fifth sacral (SIV-V) and the anterior branch of the coccygeal (CoI) spinal nerves.
The clitoris (clitoris) is a homologue of the cavernous bodies of the male penis and consists of a paired cavernous body of the clitoris (corpus cavernosum clitoridis) - right and left. Each of them begins with the crus of the clitoris (crus clitoridis) on the periosteum of the inferior branch of the pubic bone.
The coracobrachialis muscle (m.coracobrachialis) begins at the apex of the coracoid process of the scapula, passes into a flat tendon, which is attached to the humerus below the crest of the lesser tubercle at the level of attachment of the deltoid tendon.
The clavicle (clavicula) is a long, S-shaped tubular bone located between the clavicular notch of the sternum medially and the acromial process of the scapula laterally.
The ciliary body (corpus ciliare) is the middle thickened part of the vascular tract of the eye, which produces intraocular fluid.
Choroid (from Latin chorioidea) is the vascular membrane itself, the posterior part of the vascular tract of the eye, located from the dentate line to the optic nerve.
The chewing muscles develop on the basis of the first visceral (lower jaw) arch. These muscles originate on the bones of the skull and are attached to the lower jaw - the only movable bone, providing a variety of movements in humans in the temporomandibular joint.
The chest muscles are arranged in several layers. More superficial are those muscles that develop in connection with the formation of the upper limb. They connect the upper limb to the chest. These include the pectoralis major and the anterior serratus muscles.
