Anatomy Flashcards
A patient with an isolated oculomotor nerve paralysis
would present with the following findings on the affected
side
a. Constricted pupils
b. Weakness of eyelid closure
c. Eyelid deviated laterally
d. All of the above
c. Eyelid deviated laterally
Contestable: According to 5th Moore’s Anatomy, the ff are the
actions of the oculomotor nerve: Motor to superior rectus,
inferior rectus, medial rectus, inferior oblique, and levator
palpebrae superioris muscles; raises superior eyelid; turns
eyeball superiorly, inferiorly, and medially, parasympathetic
innervation to sphincter of pupil and ciliary muscle; constricts
pupil and accommodates lens of eye.
In fact, usual findings of isolated oculomotor nerve palsy:
Dilated pupil; ptosis; eye turns down and out; pupillary reflex
on the side of the lesion will be lost
Following this, you might not actually find any of the above –
you would have dilated pupils, supero-lateral eyeball deviation,
and lagopthalmos (poor eye opening).
Reproductive adaptations noted in the female true pelvis
include the following EXCEPT
a. Greater pubic angle
b. Longer pelvic cavity
c. Wider sacrosciatic notches
d. Cylindrical pelvic cavity
b. Longer pelvic cavity
Females have a shorter (wide and shallow) pelvic cavity
A high velocity bullet penetrates the posterior aspect of
the shoulder and severely injures the origin of the
posterior cord of the brachial plexus. Each of the following
nerves might possibly be affected EXCEPT the
a. Upper subscapular
b. Thoracodorsal
c. Radial
d. Medial pectoral
d. Medial pectoral
Medial pectoral nerve arises from the medial cord.
During the proliferative phase of the menstrual cycle, one can observe that
a. The endometrium thickens largely because of edema
b. Glycogen disappears in the basal cytoplasm of the glandular epithelium
c. There is a two to threefold increase in the thickness of the endometrium
d. The endometrial glands become quite tortuous
C
Bile formed by hepatic cells is first secreted into the
a. Bile canaliculi
b. Space of Disse
c. Bile ducts
d. Hepatic duct
A
For the curious: space of Disse is the perisinusoidal space, where most of the lymph is formed – it drains to the deep lymphatics surrounding the intralobular portal triads.
The landmark structure noted during the dissection of the gluteal area
a. Gluteus medius
b. Quadratus femoris
c. Piriformes
d. Obturator externus
C
Semen is composed of products produced by all of the following EXCEPT the
a. Seminiferous tubules
b. Bulbourethral glands
c. Seminal vesicles
d. Rete testis
D
Contestable: The rete testis, according to Berne, does not seem to produce anything – but it is where the tubules drain, which means your sperm may come from there. Meanwhile, the bulbourethral glands empty into the urethra before ejaculation and emission, but is not technically a component of semen.
Your choice.
This structure is highly vulnerable in cancerous growth of R pulmonary hilum and posterior mediastinum
a. Trachea
b. Vagus nerve
c. Superior intercostals vein
d. Pulmonary ligament
Structures at hilum: bronchi (and associated bronchial vessels), pulmonary arteries, superior and inferior pulmonary veins, the pulmonary plexuses of nerves (sympathetic, parasympathetic, and visceral afferent fibers), and lymphatic vessels
Structures at posterior mediastinum: thoracic aorta, thoracic duct and lymphatic trunks, posterior mediastinal lymph nodes, azygos and hemiazygos veins, and esophagus and esophageal nerve plexus. Plus, possibly (nearby, but not part) thoracic sympathetic trunks and thoracic splanchnic nerves.
A patient was noted to have atrophy of the temporalis and masseter muscles on one side of the face. His corneal reflex on the affected side was normal and he had no sensory deficit in the cheek area. This patient most probably has a lesion involving the
a. Mandibular division of CN V
b. Maxillary division of CN V
c. Ophthalmic division of CN V
d. Terminal branches of CN VII
A
The primary hip flexor is the
a. sartorius
b. Rectus femoris
c. iliopsoas
d. Pectineus
C
A patient presented with complete paralysis of one side of the face with intact lacrimation and taste sensation (anterior 2/3 of tongue). The cranial nerve involved in this case most probably has a tension at the level of the
a. Internal auditory meatus
b. Stylomastoid foramen
c. Geniculate ganglion
d. External auditory meatus
b. Stylomastoid foramen
This structure is highly vulnerable in surgical manipulation of the ductus arteriosus
a. esophagus
b. left vagus nerve
c. left bronchus
d. left recurrent laryngeal nerve
d. left recurrent laryngeal nerve
The three types of granulocytes usually can be distinguished best under the light microscope on the basis of
a. Nuclear morphology and cell size
b. Nuclear morphology only
c. Cell size only
d. Staining reaction of cytoplasmic granules
d. Staining reaction of cytoplasmic granules
The liver is anatomically divided into right and left unequal halves along the fissure of the
a. Ligamentum venosum
b. Falciform ligament
c. Inferior vena cava
d. Porta hepatic
b. Falciform ligament
Both skeletal and smooth muscle can be found in the muscularis externa of the
a. stomach
b. colon
c. duodenum
d. esophagus
d. esophagus
Since the first part of swallowing is under voluntary control, bundles of skeletal muscle predominate in the muscularis of the upper third of the oesophagus- Wheater’s Histology. (Hindi anatomy!)
