2- Course of the axons:

corona radiata, then run in the posterior limb of the internal capsule.
 The fibers pass through the middle three fifths of the crus cerebri of the midbrain, then in
the basis pontis and at last form the pyramid of medulla.
 In the lower medulla most of the fibers decussate (about 80%) and cross to the opposite
side (in the motor or pyramidal decussation) to descend in the lateral white column of the spinal
cord forming the crossed pyramidal tract (Lateral corticospinal tract).
 Some fibers (about 20%) remain uncrossed and descend in the ventral white column of
the same side forming the uncrossed or direct pyramidal tract (ventral or anterior corticospinal
tract). The fibers of this last tract gradually cross to the opposite grey matter and are only
present in the upper half of the spinal cord.
3- Termination of Lateral corticospinal tracts: its crossed fibres relay on the anterior horn cells of
the opposits side of the spinal cord.
 Ventral corticospinal tract; its uncrossed fibres gradually and successively cross at each
spinal segment to relay on the anterior horn cells of the opposite side.
 Therefore each cerebral hemisphere will control the movements of the opposite side of the
body.
Second neurons: (Lower Motor Neuron)
 Is the anterior horn cells of the spinal cord.
 Their axons running in the ventral root and rami of the spinal nerves to form the motor
innervations of the voluntary muscles.

1-A- Mention the origin, insertion, nerve supply and action of the buccinator
muscle (diagram not needed) (6 marks)

 Origin:
Above : From the outer surface of the alveolar processes of the maxilla opposite the 3 molar teeth.
Below : From the alveolar processes of the mandible , close to the oblique line , opposite the 3 molar
teeth
Inbetween : From the pterygomandibular raphe, which extends from the pterygoid hamulus to the
posterior end of the Mylohyoid line.
 Insertion:
- The fibers converge towards the angle of mouth and enter
the upper and lower lips where they are arranged as follows :
* The upper fibers pass to the upper lip.
* The lower fibers pass to the lower lip.
* The middle fibers decussate where those from below
enter the upper lip and those from above enter the
lower lip.
 Nerve supply: Buccal branch of the facial nerve.
 Action:
- It compresses the cheek and lips against the teeth , so the
food is kept under immediate action of teeth .
- It helps in whistling and blowing.

3- A- Enumeratethe arteries supplying the spinal cord and discuss one of them
(diagram not needed)...(6 marks)
The spinal cord is supplied by the following arteries : any one of them
1- Anterior spinal artery:
 At first there are two arteries which arise from the 4th part of the vertebral arteries, one for
each side.
 The two arteries unite to form one anterior spinal artery which descends in the anterior
median fissure of the cord and may continue on the filum terminale.
 It gives sulcal (central) branches which run through the anterior median sulcus to supply the
right and left half of the cord.
 It supplies anterior and lateral horns of grey matter and also the bases of its posterior horns. It
also supplies the anterior and lateral white columns (anterior 2/3 of spinal cord).
2- Posterior spinal arteries:
 Are two arteries, one for each side. They arise from the 4th part of the vertebral artery.
 Each artery divides into two branches.
 The branches descend on the sides of spinal cord medial and lateral to the posterior (dorsal)
roots of the spinal nerves.
 They supply the posterior white columns and the posterior horns of grey matter (posterior 1/3
of spinal cord).
 At the conus medullaris , the anterior & posterior spinal arteries form anastmotic loops with
each other which give cauda equina arteries .
3- Radicular arteries:
 Are numerous fine branches. They arise on each side from vertebral, ascending cervical,
deep cervical, posterior intercostals, lumbar and lateral sacral arteries.
 They enter the vertebral canal through the intervertebral foramina, each artery divides into
anterior and posterior branches which follow the anterior and posterior roots of the spinal
nerve respectively.
 They supply spinal nerve roots, posterior root ganglion and anastomose with branches from
anterior and posterior spinal arteries making a plexus of arteries supplying the superficial
surface of the spinal cord called the pial plexus.

5- A- Mentionthe congenitalanomalies of the urinarybladder (5 marks)
1) Urachal fistula:
- The allantois fails to become obliterated and the urine passes out of the patent urachus to the
umbilicus.
2) Urachal cyst:
- Occurs when a localized area of the allantois persists.
- The secretory activity of the lining epithelium results in a cystic dilatation.
3) Urachal sinus:
-The proximal part of the urachus is obliterated and fibrosed, while its distal part remains patent.
- This leads to the formation of a sinus with discharge of serous fluid through the umbilicus.
4) Ectopia vesica:
- Occurs when the posterior wall of the urinary bladder is exposed to the exterior.
- It is caused by the failure of the anterior abdominal wall and anterior wall of the bladder to
develop.
- This defect is due to inability of the mesoderm of the primitive streak to migrate around the cloacal
membrane.
