What is the Difference Between Corpus Callosum and Corpus Luteum

The main difference between corpus callosum and corpus luteum is that the corpus callosum connects the right and left hemispheres of the brain, whereas the corpus luteum secretes hormones such as estrogen, progesterone, and inhibin A. 

The corpus callosum and corpus luteum are two anatomical structures that occur in the body.

What is Corpus Callosum

The corpus callosum is a large bundle of myelinated neurons. It contains more than 200 million nerve fibers. Their function is to connect two brain hemispheres. It permits the communication between the left and right hemispheres. The rostrum, the genu, the body, and the splenium are the four parts of the corpus callosum.

Furthermore, it develops ventrally from the lamina reuniens. Importantly, it is the largest commissural tract that connects the two hemispheres of the brain. It occurs beneath the cerebral cortex of the brain. However, the corpus callosum only occurs in placental mammals. It is the largest white matter structure of the brain. The length of the corpus callosum is around 10 inches.  

What is Corpus Luteum

The Corpus luteum (or Corpus Luteum Graviditatis) is the ruptured and collapsed Graafian follicle. Also, the collapsed Graafian follicle contains a blood clot and granulosa cells that are enlarged and become vesicular. Further, these granulosa cells become folded and are called granulosa lutein cells. Theca interna cells fill the space between folds. However, these cells also become glandular and are known as theca lutein cells.

Moreover, granulosa lutein cells start to secrete progesterone. The corpus luteum also secretes estrogen, which inhibits follicle-stimulating hormone (FSH), and relaxin, which relaxes the fibrocartilage of the pubic symphysis. If the pregnancy does not occur, the corpus luteum degenerates into the corpus albicans, and the levels of estrogen and progesterone fall, thus allowing the release of FSH and LH. In contrast, if pregnancy occurs, the corpus luteum persists.

Similarities Between Corpus Callosum and Corpus Luteum

• Corpus callosum and corpus luteum are two anatomical structures that occur in the body.

Difference Between Corpus Callosum and Corpus Luteum

Definition

Corpus callosum refers to a large bundle of more than 200 million myelinated nerve fibers that connect the two brain hemispheres, permitting communication between the right and left sides of the brain. In contrast, corpus luteum refers to the yellow hormone-secreting body in the female reproductive system.

Occurrence

The corpus callosum occurs in the brain, while the corpus luteum occurs in the ovary.

Function

The corpus callosum connects the right and left hemispheres of the brain, while the corpus luteum secretes hormones such as estrogen, progesterone, and inhibin A. 

FAQ: Corpus Callosum and Corpus Luteum

What is the difference between corpus callosum and corpus striatum? 

Corpus callosum is the structure that connects the two hemispheres of the brain. Meanwhile, the corpus striatum controls the movement and reward process.   

What is the difference between pons and corpus callosum? 

The corpus callosum occurs in the cerebrum, while pons occur in the cerebellum.

What is another name for the corpus luteum? 

Corpus luteum graviditatis is another name for corpus luteum. It secretes progesterone that maintains the lining of the endometrium and the embryo’s growth.

Conclusion

In brief, the corpus callosum and corpus luteum are two anatomical structures in the body. Corpus callosum occurs in the brain. It connects the right and left hemispheres of the brain. In comparison, corpus luteum occurs in the ovary. It produces hormones such as estrogen, progesterone, and inhibin A. Therefore, the main difference between corpus callosum and corpus luteum is their occurrence and function.
