1. The transverse foramen is a typical feature to all cervical vertebrae. Normally, the vertebral artery passes through the transverse foramina form the CV7 to CV1, after that, enters the vertebral canal. ( )

2. The common carotid artery branches into the external and internal carotid arteries. To the beginning parts of these two arteries, the lateral one is the internal carotid artery while the medial one is the external carotid artery. ( )

3. We define the danger triangle in the face, because there is a high chance for infections of this region to spread into the cranial cavity through the lymphatic passages. ( )

6. All the extraocular muscles share the common attachment, the tendious ring, except the inferior oblique. ( )

7. Some external features of the brainstem can be used in helping identify the locations of the deep nuclei. Deep to the hypoglossal triangle is the hypoglossal nucleus, deep to vagal triangle is the dorsal motor vagus nucleus, and deep to the facial colliculus is the facial motor nucleus. ( )

8. The hypothalamus is involved in endocrine. The infundibular nucleus can secrete a series of releasing and inhibiting hormones, and the paraventricular nucleus and supraoptic nucleus can secrete the oxytocin and vasopressin individually. ( )

9. To the inner organs, their sympathetic innervations are served by the vagus nerve, a cranial nerve, since that the spinal nerve only consists of 3 components: somatic motor, somatic sensory and visceral sensory. ( )

10. The ureter is almost half inside the abdominal cavity and half inside the pelvic cavity; its second constriction (narrow part) is at the location where it crosses over the iliac vessels. ( )

11. Anatomically, the perineum can be divided into two triangles; these two triangles are arranged in the same approximate horizontal plane. ( )

12. The ligaments of uterus are of great importance in keeping the uterus in right position, furthermore, all these ligaments are double layered peritoneal structures. ( )

13. Some spinal nerves are sensory and others are motor. ( )

14. The Broca area is ipsilateral to the Wernicke area. ( )

15. The posterior chamber, between the iris and lens, is filled with aqueous humor. ( )
III. Fill in the following blanks:( 1 marks for each, 20 marks out of 100 )

2. The is a delicate, impermeable membrane covering the brain and lying between the pia mater internally and the dura mater externally. It is separated from the dura by space, and from the pia by space, which is filled with .

3. The floor of posterior cervical triangle is supported by the , , , , and .

4. The pharynx is a muscular passage divided into , ,and .

5. The larynx has a pair of superior that exclude food and drink from the airway, and a pair of inferior that function in speech.
