C2Technical/Scientific
Definition
Meaning
A microscopic, spherical filtering unit in the kidney, consisting of a glomerulus enclosed in a Bowman's capsule, where blood filtration begins.
In anatomy, the term can also refer to similar small, rounded bodies in other tissues, such as in the spleen, but the renal usage is primary.

Common Mistakes
- Misspelling as 'malphigian' or 'malpigean'.
- Confusing it with the 'malpighian tubule' in insects.
- Using it as a standalone term without the clarifying context of 'kidney' or 'renal'.

Frequently Asked Questions
It was named after Marcello Malpighi, a 17th-century Italian physician and biologist considered a founder of microscopic anatomy.
No. The malpighian corpuscle (renal corpuscle) is the initial filtering component of a nephron. A nephron includes the corpuscle plus a long tubule for further processing.
It is located in the cortex of the kidney.
While the term is primarily renal, 'malpighian corpuscles' can also refer to small nodular masses of lymphatic tissue in the spleen, though this usage is less common.
