Question

Corpus spongiosum is a part of
A. Ovary
B. Testis
C. Uterus
D. Male copulatory organ.

Answer 1

Hint:These formations are made of a sponge-like tissue containing trabeculae, irregular blood-filled spaces lined by endothelium and separated by connective tissue septa. Behind, it is expanded to form the urethral bulb.

Complete answer:
To answer this question, first, we need to know about corpus spongiosum. In male anatomy, the corpus spongiosum is the part of penis which is a mass of erectile tissue that lies along with the exterior of the penis and is found beneath the set of corpus cavernosa, which consists of 90 percent of the blood during a normal erection. It is a smaller region compared to either of the identical corpus cavernosa.

Fig- Corpus spongiosum.
Now, let us find the solution from the option.
Corpus spongiosum, as the name suggests is a spongy mass surrounding the male urethra within the penis. It is not a part of the ovary.
In higher vertebrates like humans, the penis is male copulatory organ. The penis has a root and a body. The root lies in the perineum and the body surrounds the urethra. It is formed by three cylindrical erectile tissue mass and involuntary muscle. The erectile tissue is helped by fibrous tissue and enclosed with skin and has a high blood supply. The two lateral columns are referred to as the corpora cavernosa and the column between them, consisting of the urethra, is the corpus spongiosum. At its head, it is enlarged into a triangular structure known as the glans penis.

The male urethra provides a common pathway for the flow of urine and semen, the combined secretions of the male reproductive organs.

Thus, the correct option is D. i.e. Male copulatory organ.

Note:The corpus spongiosum penis correlates with the female vestibular bulbs. It consists of the urethra, the tube via that urine and semen released from the body, and enlarges to produce the glans penis, an enlarge cap at the top of the penis. The corpus spongiosum penis may be explained as surrounding the urethra and ends at the vertical urethral orifice.
