The paired dorsolateral columns of erectile tissue in the penis are the:
The two corpora cavernosa lie side by side dorsally. The single corpus spongiosum surrounds the urethra and expands into the bulb and glans.
Which surface of the uterine body lacks a direct peritoneal covering because the broad ligament attaches there?
Peritoneum covers the fundus and the anterior and posterior surfaces; along the lateral margins its two layers separate to form the broad ligament, leaving a bare strip.
The ovary is attached to the posterior layer of the broad ligament by a short peritoneal fold called the:
The mesovarium suspends the ovary from the broad ligament and carries its vessels. The mesosalpinx encloses the uterine tube.
Sensory and sympathetic nerve fibres reach the breast through branches of which intercostal nerves?
The breast is innervated by anterior and lateral cutaneous branches of the 4th–6th intercostal nerves.
Inside the tunica albuginea of the testis lies a vascular layer of capillaries in delicate connective tissue. What is it called?
The tunica vasculosa is the innermost capillary layer of the testis. The tunica vaginalis is a serous sac; the albuginea is a fibrous capsule.
The spermatic cord receives its nerve supply from which spinal segments?
Autonomic fibres to the testis and cord travel from T10–T11, which is why testicular pain may be referred to the periumbilical region.
Which epithelium lines the mucosa of the seminal vesicles?
The seminal vesicle mucosa is folded and lined by secretory columnar/pseudostratified columnar cells producing fructose-rich fluid.
In a young adult, the prostate gland weighs about:
A normal young adult prostate is walnut-sized and weighs about 20 g (roughly 20-25 g). It enlarges with age in benign prostatic hyperplasia; weights of 80 g or more indicate marked enlargement.
Each testicular lobule contains how many coiled seminiferous tubules?
The testis has about 200–300 lobules, each holding 1–4 highly coiled seminiferous tubules.
