Is bulbocavernosus reflex present in spinal shock?

The bulbocavernosus reflex (BCR), bulbospongiosus reflex (BSR) or “Osinski reflex” is a polysynaptic reflex that is useful in testing for spinal shock and gaining information about the state of spinal cord injuries (SCI).

Why does the bulbocavernosus reflex exist?

The bulbocavernosus reflex (BCR) is a well-known somatic reflex that is useful for gaining information about the state of the sacral spinal cord segments. When present, it is indicative of intact spinal reflex arcs (S2–S4 spinal segments) with afferent and efferent nerves through the pudendal nerve.

What is Penilo Cavernosus reflex?

In contrast to myotatic reflexes (e.g. knee or Achilles jerks), which are primarily responses to artificial and physiologically unimportant stimuli, the penilo-cavernosus reflex is assumed to have the physiological function of assisting in emptying the urethra after voiding, and of being part of the ejaculation process …

How do you elicit BCR reflex?

The bulbocavernosus reflex, which reflects the integrity of the S2 to S4 levels of the sacral cord, is elicited by gently tapping the clitoris with a cotton swab and observing the contraction of the bulbocavernosus and ischiocavernosus muscles.

How do you use bulbocavernosus reflex?

For testing of the BCR, it is required to squeeze the glans penis in men and most commonly touching the clitoris (or labium minus) in women to stimulate the reflex while checking for a reflex contraction of the external anal sphincter.

How do you test men’s bulbocavernosus reflex?

Who discovered bulbocavernosus reflex?

Bulbocavernosus reflex (BCR) Bors and Blinn first described the BCR in 1959 [14], which is also known as clitoroanal [15], penilo-cavernosus [16], and Osinski reflex [17].

What nerve Innervates the bulbospongiosus muscle?

the pudendal nerve
Bulbospongiosus is innervated by the deep branch of perineal nerve (S2-S4), which is a branch of the pudendal nerve.

What does the bulbospongiosus muscle do in females?

Function. In males it contributes to erection, the contractions of orgasm and ejaculation. In females it contributes to clitoral erection and the contractions of orgasm, and closes the vagina.
