Lyric. Lyric is a loosely defined term for a broad category of non-narrative, non-dramatic poetry, which was originally sung or recited with a musical instrument, called a lyre [see voice, sound ].Generally, lyric poets rely on personal experience, close relationships, and description of feelings as their material.t is perhaps no coincidence that a contemporary definition of lyric is the words of a popular song (OED), since in both poetry and music the words are illogically connected for sound not meaning. Drama has likewise had to redefine itself so that theatricality remains its essence (Fried; see objecthood).
Sebaceous glands produce the oily, waxy substance called sebum (Latin, meaning fat or tallow) that is made of fat , wax, and the leftover dead fat-producing cells. In the glands, sebum is produced within specialized cells and is released as these cells burst; sebaceous glands are thus classified as holocrine glands. Sebum has no smell, but its bacterial breakdown can produce a bad smell.

Acne is caused by an enlargement of the sebaceous follicles, which contain oil-producing sebaceous glands, the root cause of acne.
