| arrectores pilorum | Bundles of smooth muscle fibres, attached to the deep part of the hair follicles, passing outward alongside the sebaceous glands to the papillary layer of the corium; they act to pull the hairs erect, causing "goose bumps" or "goose flesh" (cutis anserina). Synonym: musculi arrectores pilorum, arrectores pilorum, erector muscles of hairs. (05 Mar 2000) |

| vortices pilorum | A spiral arrangement of the hairs, as at the crown of the head. Synonym: vortices pilorum. (05 Mar 2000) |
| musculi arrectores pilorum | Bundles of smooth muscle fibres, attached to the deep part of the hair follicles, passing outward alongside the sebaceous glands to the papillary layer of the corium; they act to pull the hairs erect, causing "goose bumps" or "goose flesh" (cutis anserina).

| musculus erector clitoridis | <anatomy, muscle> Origin, ramus of ischium; insertion, corpus cavernosum penis (or clitoridis); action, compresses the crus of the penis (or clitoris) forcing blood in its sinuses into the distal part of the corpus cavernosum; nerve supply, perineal. Synonym: musculus ischiocavernosus, musculus erector clitoridis, musculus erector penis. (05 Mar 2000) |
| musculus erector penis | <anatomy, muscle> Origin, ramus of ischium; insertion, corpus cavernosum penis (or clitoridis); action, compresses the crus of the penis (or clitoris) forcing blood in its sinuses into the distal part of the corpus cavernosum; nerve supply, perineal. Synonym: musculus ischiocavernosus, musculus erector clitoridis, musculus erector penis. (05 Mar 2000) |
| musculus erector spinae | Origin, from sacrum, ilium, and spines of lumbar vertebrae; it divides into three columns, iliocostalis musculus, longissimus musculus, and spinalis musculus, which insert into ribs and vertebrae with additional muscle slips joining the columns at successively higher levels; action, extends vertebral column; nerve supply, dorsal primary rami of spinal nerves. Synonym: musculus erector spinae, erector muscle of spine, musculus sacrospinalis. (05 Mar 2000) |
| erector | 1. One who, or that which, erects. 2. <anatomy> A muscle which raises any part. 3. <physics> An attachment to a microscope, telescope, or other optical instrument, for making the image erect instead of inverted. Source: Websters Dictionary (01 Mar 1998) |
