Q #01…Describe the female reproductive system. Begin by first identifying
significant anatomical parts and explaining what role each organ plays in the
reproductive process. Then, name important pathology that afflict those particular
anatomical parts just named. Also, choose which laboratory tests and diagnostic
procedures would be used in compliance with that specific pathology.
Answer:
The reproductive system in women is contained mainly in the pelvic cavity and
perineum, although during pregnancy, the uterus expands into the abdomen cavity.
Major components of the system consist of:


an ovary on each side; and
a uterus, vagina, and clitoris in the midline
In addition, a pair of accessory glands (the greater vestibular glands) is associated with
the tract.
Different Parts and Functions of Female reproductive system:
Pathologies and their laboratory Test:
Ovaries:
There are two well known pathologies of ovaries i.e.
1) Ovarian tumors.



Diagnosis is by
ultra sound
CT scan
Biopsy.
2) Polycystic ovarian syndrome.
There is a criterion for the diagnosis of PCOS i.e.
•
Rotterdam Criteria (2 out of 3)
–
Menstrual irregularity due to anovulation oligo-ovulation.
–
Evidence of clinical or biochemical hyperandrogenism.
–

Presence of 12 or more follicles in each ovary measuring 2 to 9 mm
in diameter and/or increased ovarian volume.
Other investigations include:

diseases of reproductive tract involve more than 1 part e.g. pelvic inflammatory disease
(PID) that involves endocervix, vagina, uterus, fallopian tubules.
Q #02…Explain the workings of the lymphatic system. First, begin by identifying
important anatomical parts and indicating what each organ is responsible for in the
entire system. Next, specify any diseases or pathology that afflict those specific
anatomical parts just named. Then, select the laboratory tests and diagnostic
procedures that would be used in compliance with that particular disease or
pathology.
Answer:
The lymphatic system is a network of tissues and organs that primarily consists of
lymph vessels, lymph nodes and lymph. A network of vessels, tissues, organs, and cells
constitute the lymphatic system. Included in this network are lymph vessels, lymph
nodes, the spleen, the thymus, and lymphocytes. Running throughout this network is
watery fluid called lymph.
The major components of the lymphatic system include lymph, lymphatic vessels, and
lymphatic organs that contain lymphoid tissues.
Components of the Lymphatic System and their functions:
Components of lymphatic system
1. Lymph:
– a fluid similar to plasma
– does not have plasma proteins
2. Lymphatic vessels (lymphatics):
– network that carries lymph from peripheral tissues to the venous system
3. Lymphocytes, phagocytes, and other immune system cells
4. Lymphoid tissues and lymphoid organs:
– found throughout the body
Function of the Lymphatic System
• Collection of fluid and solutes lost by the capillaries
– 3.6L/day
• Distribution
– Hormones
– Waste products
• Protects us against disease
– Production, maintenance and distribution of lymphocytes.
The lymphatic system’s main functions are as follows:



Restoration of excess interstitial fluid and proteins to the blood
Absorption of fats and fat-soluble vitamins from the digestive system and transport of
these elements to the venous circulation
Defense against invading organisms
Diseases and their diagnostic tests:
There are many diseases related to lymphatic system but some are as follow:
1)
2)
3)
4)
5)
6)
7)
Lymphedema
Hodgkin's lymphoma

Elephantiasis
Lymphangiosarcoma
Lymphatic filiaris
Lymphoid leukemias and lymphomas
We can diagnose these conditions by









CT scan

Fine needle aspiration (FNA) or core needle biopsy
Bone marrow biopsy
Positron Emission Tomography (PET scan)
Immunohistochemistry
Complete blood count
microscopic examination for lymphatic filiaris

to see the metastatic lymph nodes we can do chect X-ray, ultrasound, bone
scan, MRI, pleural fluid tap, lumbar puncture, etc
Q #03…Examine the male reproductive system. Start by identifying key
anatomical parts and explaining what each organ is responsible for in the body
system. Then, indicate any diseases or pathology that afflicts those particular
anatomical parts just named. After indicating the diseases or pathology, decide
which of the laboratory tests and diagnostic procedures would be used in
compliance with that specific disease or pathology.
Answer:
The male reproductive system includes the two testes, the system of ducts that store
and transport sperm to the exterior, the glands that empty into these ducts, and the
penis. The duct system, glands, and penis constitute the male accessory reproductive
organs. The reproductive system in men has components in the abdomen, pelvis, and
perineum. The major components are a testis, epididymis, ductus deferens, and
ejaculatory duct on each side, and the urethra and penis in the midline. In addition,
three types of accessory glands are associated with the system:




a single prostate;
a pair of seminal vesicles; and
a pair of bulbourethral glands.

Q #04...Explore the musculoskeletal system. Begin by first matching the medical
term with the more commonly known term for the anatomical parts. For example,
“clavicle” is more commonly known as “collar bone” and “patella” is more often
called the “knee cap.” Then, name important pathology that afflict those
particular anatomical parts just named. Also, choose which laboratory tests and
diagnostic procedures would be used in compliance with that specific pathology.
Answer:
Musculoskeletal system is the system of muscles and tendons and ligaments and
bones and joints and associated tissues that move the body and maintain its form.
The musculoskeletal system includes the bones, joints, muscles, and tendons. The
resident looked for abnormalities and muscle wasting. Knowing which areas are
wasted identifies the nerve that supplies them. The musculoskeletal system of an
adult contains more than 200 bones and 600 muscles. Some of these are the
cranium, clavicle, scapula, sternum, humerus, ulna, radium, sacrum, pelvis, femur,
patella, fibula, tarsals, orbicularis oculi, platysma, trapezius, deltoid, pectoralis
major, biceps brachii, gluteus medius, adductor magnus, soleus, gluteus maximus,
gastrocnemius, and Achilles tendon
