CVS; the anatomy of local circulatory system in the head and neck region

1. Practical anatomy CVS/ circulatory system blood vessels of head and neck C.O.A Session; 9th session; pages; 35-36, 635-650, 678-680. References; C.O.A By Richard Snell & Frank Netters atlas

2. CVS/ SC Compartments; heart and blood vessels ( A, C and V) and blood Closed system/ hemostasis vs. homeostasis Types; systemic, pulmonary, coronary, portal and fetal Functions!?

3. There are three main types of arteries: Elastic arteries. Muscular arteries. Arterioles. Anastomosis vs end arteries Coronary arteries: Heart. Carotid arteries: Brain, head, face and neck. Vertebral arteries: Brain and spine. Iliac arteries: Pelvis. Types of Veins; Pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart. Systemic veins return oxygen-depleted blood from the rest of the body to the right atrium of the heart. Superficial veins are located close to the surface of the skin and are not located near a corresponding artery.

4. Blood vessels of the head and neck Arteries of the head and neck; Common carotid arteries (CCA); Rt. Is shorter than Lt. !? a. ECA ; External carotid arteries B. ICA ; Internal carotid arteries Vertebral arteries (VA)……..source; SCA

5. The carotid sheath is a condensation of the deep cervical fascia, or fibrous connective tissue of the neck, which surrounds the great vessels of the neck. It extends from the base of the skull caudally to the first rib on the sternum.

6. The external carotid artery begins at the bifurcation from the common carotid, lateral to the upper border of the thyroid cartilage, between C3 and C4 . The external carotid is situated anteromedial of the internal carotid.

7. Ventral branches Superior thyroid: muscles of hyoid region, larynx and vocal folds, and thyroid gland Lingual: tongue, muscles of the tongue, and salivary glands below the tongue Facial: pharynx, palate, chin, lips, and nose Medial branch Ascending Pharyngeal: pharyngeal area and various lymph nodes Posterior branches Occipital: scalp on the back of the skull and various muscles in the neck Posterior auricular: ear and scalp over ear Terminal branches Maxillary: teeth and gums, the muscles of mastication, the nasal cavity, the eyelids, and the meninges Superficial temporal: temporal fascia and muscle, parotid gland

8. The pulse from the carotids may be felt on either side of the front of the neck just below the angle of the jaw.
