pal·mar arch
(pahl'măr ahrch)1. Deep palmar arch; the arterial arch located deep to the long flexor tendons in the hand, formed by the radial artery and the deep palmar branch of the ulnar artery.
Synonym(s): arcus palmaris profundus [TA] .
Synonym(s): arcus palmaris profundus [TA] .
2. Superficial palmar arch; the arterial arch in the hand located superficial to the long flexor tendons, formed principally by the ulnar artery and usually completed by a communication with the superficial palmar branch of the radial artery.

arch
(arch) [L. arcus, a bow]An anatomical structure having a curved or bowlike outline. See: arcus
abdominothoracic arch
The anterior and lateral boundary between the line dividing the thorax and the abdomen.
Synonym: costal archalveolar arch
The arch of the alveolar process of either jaw (maxillary and mandibular arch).
aortic arch
Any of a series of six pairs of vessels that develop in the embryo and connect the aortic sac with the dorsal aorta. During the fifth to seventh weeks of gestation, the arches undergo transformation, some persisting as functional vessels, others persisting as rudimentary structures, and some disappearing entirely.
axillary arch
An anomalous muscular slip across the axilla, between the pectoralis major and latissimus dorsi muscles.
branchial arch
Any of five pairs of arched structures that form the lateral and ventral walls of the pharynx of the embryo. The first is the mandibular arch; the second is the hyoid arch; the third, fourth, and fifth arches are transitory. They are partially separated from each other externally by the branchial clefts and internally by the pharyngeal pouches. They are important in the formation of structures of the face and neck.
Synonym: pharyngeal archcarotid arch
The third aortic arch, which provides the common carotid artery.
costal arch
Abdominothoracic arch.crural arch
The inguinal ligament, which extends from the anterior superior iliac spine to the pubic tubercle. Synonym: Poupart's ligament
deep crural arch
A band of fibers arching in front of the sheath of femoral vessels; the downward extension of the transversalis fascia.
deep palmar arch
An arch formed in the palm by the communicating branch of the ulnar and the radial artery.
dental arch
The arch formed by the alveolar process and teeth in each jaw (maxillary and mandibular arch). Synonym: arcus dentalis
arch of foot
Any of the four vaulted structures in the foot: the internal (medial) longitudinal, the outer (lateral) longitudinal, and two transverse.
glossopalatine arch
The anterior pillar of the fauces; one of two folds of mucous membrane extending from the soft palate to the sides of the tongue.
hemal arch
1. In lower vertebrates, extensions from the lateral areas of the caudal vertebrae that fuse to enclose the caudal artery and vein. In humans these are represented by the costal processes of the vertebrae.
2. An arch formed by the body and dorsal processes of a vertebra.
hyoid arch
The second branchial arch, which gives rise to the styloid process, the stylohyoid ligament, and the lesser cornu of the hyoid bone.
inferior tarsal arch
The arch of the median palpebral artery that supplies the lower eyelid.
longitudinal arch
The anteroposterior arch of the foot; the medial portion is formed by the calcaneus, talus, navicular, the three cuneiform bones, and the first three metatarsals; the lateral portion is formed by the calcaneus, cuboid, and the fourth and fifth metatarsals.
mandibular arch
1. The curved composite structure of natural dentition and supporting tissues of the mandible.
2. The residual bony ridge after teeth have been lost from the mandible.
maxillary arch
The curved composite structure of the natural dentition and supporting tissues of the upper jaw (maxillary and mandibular arch); the residual bony ridge after teeth have been lost from the upper jaw.
nasal arch
An arch formed by the nasal bones and by the nasal processes of the maxilla.
neural arch
Vertebral arch.palatopharyngeal arch
Pharyngopalatine arch.palmar arch
See: deep palmar arch; superficial palmar archpharyngeal arch
Branchial arch.pharyngopalatine arch
The posterior pillar of the fauces; one of two folds of mucous membrane extending from the soft palate to the sides of the pharynx. The palatine tonsil lies in the front of the pharyngopalatine and behind the palatoglossal arch. Synonym: palatopharyngeal arch
plantar arch
The arch formed by the external plantar artery and the deep branch of the dorsalis pedis artery.
pubic arch
The arch formed by the rami of the ischia and pubic bones. It forms the anterior portion of the pelvic outlet.
pulmonary arch
The fifth aortic arch on the left side. It becomes the pulmonary artery.
superciliary arch
A curved process of the frontal bone lying just above the orbit, subjacent to the eyebrow, and directly above the supraorbital notch.
Synonym: superciliary ridgesuperficial palmar arch
An arch in the palm forming the termination of the ulnar artery.
superior tarsal arch
The arch of the median palpebral artery that supplies the upper eyelid.
supraorbital arch
A bony arch formed by the upper margin of the orbit.
tarsal arch
See: inferior tarsal arch; superior tarsal archthyrohyoid arch
The third branchial arch, which gives rise to the greater cornu of the hyoid bone.
transverse arch
The transverse arch of the foot formed by the navicular, cuboid, cuneiform, and metatarsal bones.
vertebral arch
The arch formed by the posterior projection of a vertebra that, with the body, encloses the vertebral foramen. Synonym: neural arch
zygomatic arch
The formation, on each side of the cheeks, of the zygomatic process of each malar bone articulating with the zygomatic process of the temporal bone.
