Question 1

what is the ejaculatory duct

Answer 1

formed by the union of the vas deferens with the duct of the seminal vesicle. They pass through the prostate, and open into the urethra at the seminal colliculus.

Question 2

what is the epididymis

Answer 2

The epididymis is a long, coiled tube that stores sperm and transports it from the testes

Question 3

what is the prostatic urethra

Answer 3

The prostatic urethra is the portion of the urethra that traverses the prostate. It originates in the region of the bladder neck, courses roughly 2.5 cm inferiorly, and terminates at the membranous urethra

Question 4

what is the rete testis

Answer 4

The rete testis is a network of tubules in the mediastinum testis that carry sperm from the seminiferous tubules to the efferent ducts.

Question 5

what is the penile urethra

Answer 5

Passes through the bulb and corpus spongiosum of the penis, ending at the external urethral orifice

Question 6

what is the seminal vesicle

Answer 6

The seminal vesicles are accessory glands of the male reproductive system. They are a pair of contorted or twisted tubes, which are located between the bladder and the rectum. At puberty, the seminal vesicles form sacs and contribute up to 85% of the seminal fluid.

Question 7

what is the seminiferous tubules

Answer 7

Seminiferous tubules are located within the testes, and are the specific location of meiosis, and the subsequent creation of male gametes, namely spermatozoa.

Question 8

what are vas deferons

Answer 8

these ducts transport sperm from the epididymis to the ejaculatory ducts

Question 9

what is the hyoid

Answer 9

The hyoid bone is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. At rest, it lies at the level of the base of the mandible in the front and the third cervical vertebra (C3) behind.

Question 10

what is the ilium bone

Answer 10

the ilium bone is the uppermost and largest part of the hip bone

Question 11

what is the falciform ligament

Answer 11

The falciform ligament is a ligament that attaches the liver to the front body wall, and separates the liver into the left medial lobe and right lateral lobe.

Question 12

what is the greater omentum

Answer 12

The greater omentum attaches the stomach to the transverse colon. It covers the small intestines like an apron

Question 13

what is the lesser omentum

Answer 13

The lesser omentum attaches the stomach and the duodenum to the liver.

Question 14

what is the greater sac and the lesser sac

Answer 14

The peritoneal cavity can be divided into the greater and lesser peritoneal sacs. The greater sac comprises the majority of the peritoneal cavity. The lesser sac (also known as the omental bursa) is smaller and lies posterior to the stomach and lesser omentum.

Question 15

what is the triangular ligament

Answer 15

The triangular ligaments are asymmetrical bilateral structures that help to hold the liver in place. There are two in total, right and left, both of which are continuations of the coronary ligament.

Question 16

what is the somatic nervous system

Answer 16

somatic nervous system is a component of the peripheral nervous system associated with the voluntary control of the body movements via the use of skeletal muscles

Question 17

what does the pelvic splanchnic nerve innervate

Answer 17

The pelvic splanchnic nerves contribute to the innervation of the pelvic and genital organs. The nerves regulate the emptying of the urinary bladder, control opening and closing of the internal urethral sphincter, influence motility in the rectum as well as sexual functions like erection. sigmoid colon

Question 18

where do the pelvic splachnic nerves arise

Answer 18

The pelvic splanchnic nerves also known as nervi erigentes are preganglionic (presynaptic) parasympathetic nerve fibres that arise from S2, S3 and S4 nerve roots of the sacral plexus

Question 19

what does retroperitoneal mean

Answer 19

The retroperitoneal space (retroperitoneum) is the anatomical space (sometimes a potential space) behind (retro) the peritoneum. It has no specific delineating anatomical structures. Organs are retroperitoneal if they have peritoneum on their anterior side only

Question 20

what are retroperitoneal structures

Answer 20

Retroperitoneal structures include the rest of the duodenum, the ascending colon, the descending colon, the middle third of the rectum, and the remainder of the pancreas. Other organs located in the retroperitoneal space are the kidneys, adrenal glands, proximal ureters, and renal vessels.
