this type of cancer begins in the glandular tissue of body, in the breast this cancer originates in either the lobules (lobular Carcinoma) or the ducts (Ductal Carcinoma)
Ductal Carcinoma in Situ (DCIS)
found in milk ducts and has not spread to the walls and is almost 100% curable if detected early by mammogram. if not treated can become invasive
Invasive Ductal Carcinoma (IDC)
80% of breast cancers fall into this category. Can metastasize if left through lymphatics
Lobular Carcinoma in Situ (LCIS)
considered neoplasm found in lobules in breast.
more of a precancer but if diagnosed with this you have more of a chance of progression
Invasive Lobular carcinoma (ILC)
10-15% of breast cancers. originates in glands of breast and spread into fatty tissue with potential to metasasize
Breast is removed to the retromammary space
Breast, pectorals, fat and lymph nodes are removed
Current popular treatment, tumor and surrounding tissue and radiation

What type of pelvic fracture occurs during a car accident?
Anterior-posterior compression of the pelvis results in a fracture of the public rami

Urinary - Ureters Bladder and Urethra
Reproductive - Male = Ductus deferens, Seminal vesicles and prostate gland... Female = Ovaries, Uterus, and Uterine Tubes, Vagina.
What are the structures filing the the true pelvis are considered?
What is the anterior Pelvic Wall consist of?
Pubic Rami and Pubic Symphysis

Funnel shaped pelvis diaphragm

Levator Ani (iliococcygeus, pubococcygeus, puborectalis)
Between the pubic bone and the bladder
between the rectum, sacrum and coccyx
Retrouterine Pouch aka "pouch of douglas"
Vesico-Uterine in females
What does the diamond shaped perineum contain?
Anal (posterior) triangle contains the anus and posterior part of the pelvic diaphragm
Urogenital (anterior) Triangle
What is the relationship between the large intestine and the pelvis and perineum?
Large Intestine enters the pelvis as the sigmoid colon mid way down the sacrum it loses its mesentery and becomes the Rectum
attach the body of the penis to the line alba and the pubic symphysis?
Fundiform and Suspensory ligaments
Foreskin or prepuce
double layer of skin which covers the glans and separates the glans from the body at the neck of the penis
What are the sensory fibers of the penis?
Ilio-inguinal nerves and pudendal nerves
Parasympathetic causes what in the penis?
Arteries in the tissues dilate causing an Erection
Sympathetic cause what in the penis?
Arteries of the tissues constrict causing Ejaculation
What does the sympathetic L1-L2 cause?
closure of the vesical sphincter at the neck of the bladder
What does the parasympathetic S2-S4 cause?
contraction of the urethral muscle
What do the pudendal nerves (S2-S4) cause in the penis?
contraction of the bulbospongious muscle
external urethral orifice is on the ventral surface of glands penis
when the prepuce of the penis fits tightly around the glands and can not be retracted
Smegma which are cheesy secretions of the prepuce gland accumulate in the prepubital sac causes irritation and swelling.... blood flow and tissue fluid are interfered with
What is done to correct a Paraphimosis?
A circumcision will be performed
produces ova and steroid hormones
Where does the Fertilization takes place?
What are 3 layers of the Uterus?
1) Serous outing Coat
2) Very Thick Muscular Layer
3) Inner Mucosa (Endometrium)
What is the position of the uterus?
Anteverted, retroverted and mid position
Ligaments in vagina
thickening and folds of the peritoneum covering the superior aspect of the females internal genitalia are called
What is the broad ligament?
Double layered lateral continuation of the peritoneum covering the uterus
What structures can you find in the Broad ligament?
the fallopian tubes and the ovary
Secondary mesentery for the ovary and the uterus
thickening running from the ovary toward the pelvic brim and containing the ovarian vessels
Fibrous structure which runs in the broad ligament from the uterus to and through the iguinal canal and the ends up in the labium majora
Anterior to the pubic symphysis and eminence underlying the fatty connective tissue
Surrounded by the external genitalia
Runs Posteriorly to the mons on each side and is elongated cutaneous fold
Medial to each of the labia majora is a thin fold of cutaneous tissue
What nerves innervate the pelvis?
The sacral and coccygeal nerves
What is the nervous system for the pelvis?
Pelvic Autonomic Nervous System
Arises from the lumbar plexus L2-L4 through the obturator canal supplying the thigh muscles. NO PELVIC STRUCTURES
What are the 2 main nerves of the sacral plexus?
Pudendal and Sciatic
Supply a small area of skin in the coccygeal region. It lies on the pelvic surface of the coccygeus muscle
Four main arteries that enter the lesser pelvis?
Internal Iliac (paired)
Median Sacral (unpaired)
Superior Rectal Arteries (unpaired)
carries deoxygenated blood to the placenta from the fetus
Inferior Gluteal Artery
Exits through the greater sciatic foramen to reach the gluteal region. Pelvic branches supply the bone and the muscle of the pelvic wall
Middle Rectal Artery
Supplies inferior part of the rectum, anastamoses with
the superior and inferior rectal arteries. Also supplies the seminal vesicles prostate and vagina
Supplies the vagina, uterus, and fallopian tubes
Inferior Vesicular Artery
distributed to the fundus of the bladder. In males, it also supplies the prostate and the seminal vesicles.
Supplies the vagina, uterus and fallopian tubes
What does the Internal Pudendal Artery give rise to?
Inferior Rectal Artery
Dorsal Artery of Penis
Posterior Scrotal Artery
Superior Gluteal Artery
Supplies the gluteal muscles in the buttocks
iliac branch supplies the iliacus and ilium and lumbar branch supplies the psoas major and quadratus lumborum
Lateral Sacral Artery
Supply the skin overlying the sacrum and the erector spinous muscles
descends to supply the ovary and anastomose with the uterine artery
Any abnormal increase in pressure in the valveless portal system may cause enlargement of the superior rectal veins resulting in an increase in bloodflow to the internalrectal vessels
