Tulang penis
Penis atau secara harfiah penis adalah pendukung anis mamalia berplasenta.[1] Meski pada manusia tulang ini telah hilang, tetapi baculum masih ditemukan di primata, misalnya gorila dan simpanse.
Baculum biasanya ditemukan di atas saluran uretra dan membantu perkembangbiakan seksual dengan mempertahankan ereksi lebih lama dan lebih keras.
Pada betina, homolog dari baculum adalah baubellum atau os clitoridis atau tulang klitoris.
