2 PITUITARY GLAND

3 Anatomy team Which one of the following cranial fossa is the site of pituitary gland?? A.Anterior cranial fossa. B.Middle cranial fossa. C.Posterior cranial fossa.

4 Anatomy team pituitary gland lies in the hypophyseal fossa of which one of the following bones of skull ?? A.frontal bone. B.temporal bone. C.sphenoid bone. D.ethmoid bone It is well protected in sella turcica (hypophyseal fossa) of body of sphenoid

5 Anatomy team which one of the following structures is posterior to the pitutary gland?? A.optic chiasma B.mammillary bodies C.diaphragma sellae D.cavernous sinuses (anterior) (posterior) (superior) (lateral)

6 Anatomy team which one of the following meninges represent the diaphragma sellae that cover the pitutary gland (superior relation )?? A. pia matter B. arachnoid matter C. dura matter Diaphragma sellae : A fold of dura mater covers the pituitary gland & has an opening for passage of infundibulum (pituitary stalk) connecting the gland to hypothalamus

7 Anatomy team which one of the following air sinuses lies inferiorly to the pitutary gland?? A. frontal sinuses B. sphenoidal sinuses C. ethmoid sinuses D. maxillary sinuses

8 Anatomy team IMPORTANT RELATIONS OF THE PITUTARY GLAND ANTERIOR : optic chiasma POSTERIOR : mamillary bodies SUPERIOR: Diaphragma sellae INFERIOR: Sphenoidal air sinuses LATERAL: Cavernous sinuses

9 Anatomy team which one of the following lobes of pitutary gland connect to HYPOTHALAMUS through hypothalamo-hypophyseal tract?? A. anterior lobe (Adenohypophysis) B. posterior lobe (Neurohypophysis)

10 Anatomy team Superior & inferior hypophyseal arteries (arterial supply of pitutary gland ) branchs of? A. common carotid artery B. external carotid artery C. internal carotid artery D. basilar artery In the cavernous sinuses (near the pituitary gland)

11 Anatomy team infundibulum (pituitary stalk) supply by?? A. inferior hypophyseal artery B. superior hypophyseal artery Supplies posterior lobe supplies infundibulum &form sinusoids into the anterior lobe of pituitary gland (hypophyseal portal system).

12 Anatomy team Which one of the following venous sinuses drains hypophyseal veins? A.Superior sagittal B.Cavernous C.Transverse D.Sigmoid

13 THYROID & PARATHYROID GLANDS..

14 Anatomy team Which of the following tracheal cartilage located behind isthmus of thyroid gland: a. 1st,2nd and 3rd tracheal rings b. 2nd,3rd and 4th tracheal rings c. 3rd,4th, and 5th tracheal rings d. 4th,5th and 6th tracheal rings

15 Anatomy team apex isthmus base Each lobe is pear shape the oblique line of the thyroid cartilage at the 4th or 5 th tracheal ring. in front of the 2 nd 3 rd & 4 th rings of the trachea

16 Anatomy team Thyroid gland surrounded by 2 membranes. It’s capsule and..?? A.Investing layer. B.Pretracheal layer. C.Prevertebral layer D.carotid sheath

17 Anatomy team Pyramidal lobe is connected to hyoid bone by a fibrous or muscular band called?? A.Thyrohyoid B.levator glandulae thyroideae. C.Sternohyoid D.Coricohyoid

18 Anatomy team Which of the following muscles lies anterolaterally to the thyroid gland?? A.Inferior belly of omohyoid. B.Sternohyoid C.Coricohyoid D.levator glandulae thyroideae. Anterolaterally: (4 S). 1. Sternothyroid. 2. Sternohyoid. 3. Superior belly of omohyoid 4. Sternomastoid.

19 Anatomy team Which one of the following is posterior to thyroid gland?? A. Sternomastoid B. Recurrent laryngeal nerves C. Trachea D. Common carotid artery Carotid sheath and it’s content are posterior to the thyroid gland:  Common carotid artery below & internal carotid artery above.  Internal jugular vein.  Vagus nerve.  Deep cervical lymph node

20 Anatomy team Which one of the following is medial to thyroid gland?? A. Sternomastoid B. vagus nerve C. Trachea D. Common carotid artery Posteromedially (medially):  Above: Larynx & pharynx  Below: Trachea & esophagus  Recurrent laryngeal nerve (between trachea & esophagus).  Cricothyroid muscle.  External laryngeal nerve.

21 Anatomy team Inferior thyroid artery branch of ?? A. Internal carotid artery B. External carotid artery C. Thyrocervial of subclivan artery D. Aortic arch

22 Anatomy team After thyroidectomy, the patient complained of horsiness of his voice. when the surgeon ligation the superior thyroid artery he damaged the nerve near to it ?? Which one of the following nerve is endanger in ligation of the superior thyroid artery? A. External laryngeal B. Recurrent laryngeal. C. Internal laryngeal. D. Superior laryngeal Superior thyroid artery + External laryngeal nerve Inferior thyroid artery + Recurrent laryngeal nerve

23 Anatomy team Middle thyroid vein drans into?? A.internal jugular vein B. External jugular vein C. Left brachiocephalic vein D. Right brachiocephalic vein

24 Anatomy team where are the two superior parathyroid gland site in relation to the thyroid gland? A. At superior of the posterior border of the gland. B. at the middle of the posterior border of the gland. C. at the inferior of the posterior border of the gland. 2 superior parathyroid at the middle of the posterior border of the gland. 2 inferior parathyroid at the level of the inferior pole

25 Anatomy and embryology teams Most of thyroglossal duct cysts are located in: A) inferior to hyoid bone B) Superior to hyoid bone C) Lateral to hyoid bone D) Medial to hyoid bone

26 Anatomy and embryology teams The thyroid glands reaches its final position in: A) 6th week B) 7th week C) 8th week D) 9th week

27 Anatomy and embryology teams There are pharyngeal pouches: A) 4 pharyngeal pouches B) 3 pharyngeal pouches C) 4 pairs of pharyngeal pouches D) 3 pairs of pharyngeal pouches
