Bone Marking TYPES For more tips, check out The A&P Student theAPstudent.org Basic concepts for understanding bone “geography” TERM PRONUNCIATION DESCRIPTION/TRANSLATION Angle ANG-gul An inside or outside corner Body BOD-ee The main or central portion of a bone Border BOHR-der Edge or boundary of a bone Condyle KON-dyle Rounded bump; usually fits into a fossa on another bone to form a joint [literally knuckle] krest Moderately raised ridge; generally a site for muscle attachment [literally tuft or comb] Epicondyle ep-i-KON-dyle Bump near a condyle; often gives the appearance of a “bump on a bump”; for muscle attachment [literally upon a knuckle] Facet fah-SET or FASS-et Crest Fissure FISH-ur Foramen (pl., foramina or foramens) foh-RAY-men or FO-ra-men (foh-RAM-in-ah or foh-RAY-menz) Flat surface that forms a joint with another facet or flat bone [literally little face] Long, cracklike hole for blood vessels / nerves [literally a split] Round hole for vessels and nerves [literally hole] 1 EXAMPLES Angle of mandible Inferior angle of scapula Lateral angle of scapula Superior (medial) angle of scapula Subpubic angle Body of sphenoid bone Body of mandible Body of vertebra Body of sternum Body of rib Superior border of scapula Medial (vertebral) border of scapula Lateral (axillary) border of scapula Occipital condyle Lateral condyle of femur Medial condyle of femur Lateral condyle of tibia Medial condyle of tibia Iliac crest of coxal (pelvic) bone Pubic crest of coxal (pelvic) bone Intertrochanteric crest of femur Crest of tibia Lateral epicondyle of humerus Medial epicondyle of humerus Lateral epicondyle of femur Medial epicondyle of femur Superior articular facet of vertebra Inferior articular facet of vertebra Superior orbital fissure of sphenoid Inferior orbital fissure of sphenoid Stylomastoid foramen of temporal bone Jugular foramen of temporal bone Supraorbital foramen of frontal bone Foramen rotundum of sphenoid bone Optic foramen of sphenoid bone Foramen ovale of sphenoid bone Foramen lacerum of sphenoid bone Foramen spinosum of sphenoid bone Foramen magnum of occipital bone Infraorbital foramen of maxilla Mandibular foramen Mental foramen of mandible Spinal foramen of vertebra Obturator foramen of coxal (pelvic) bone TERM PRONUNCIATION DESCRIPTION/TRANSLATION Fossa (pl., fossae) FOSS-ah (FOSS-ee) Depression; often receives an articulating bone [literally ditch] Head hed Distinct epiphysis on a long bone, separated from the shaft by a narrowed portion (or neck) Line (Latin linea) lyne (LEEN-ee-ah or LIN-ee-ah) Similar to a crest but not raised as much (is often rather faint) Margin MARJ-in Edge of a flat bone or flat area Meatus (pl., meatus or meatuses) mee-AYT-us (mee-AYT-us-ez) Tubelike opening or channel [literally passage] Neck nek A narrowed portion, usually at the base of a head Notch notch A V-like “cut” out of the margin or edge of a flat area Process PRAH-ses or PRO-ses Projection or raised area 2 EXAMPLES Mandibular fossa of temporal bone Jugular fossa of temporal bone Subscapular fossa Olecranon fossa of humerus Coronoid fossa of humerus Intercondylar fossa of femur Head of rib Head of humerus Head of radius Head of ulna Head of metacarpal bone Head of femur Head of fibula Head of metatarsal bone Superior nuchal line of occipital bone Inferior nuchal line of occipital bone Superior temporal line of parietal bone Inferior temporal line of parietal bone Intertrochanteric line of femur Linea aspera of femur Supracondylar lines of femur Intercondylar line of femur Supraorbital margin of frontal bone Infraorbital margin of maxilla External acoustic meatus of temporal bone acoustic meatus of temporal Internal bone Neck of mandible Neck of rib Anatomical neck of humerus Surgical neck of humerus Neck of radius Neck of femur Supraorbital notch Trochlear (semilunar) notch of ulna Radial notch of ulna Greater sciatic notch of coxal bone Lesser sciatic notch of coxal bone Intercondylar notch of femur Mastoid process of temporal bone Zygomatic process of temporal bone Styloid process of temporal bone Temporal process of zygomatic bone Alveolar process of maxilla Palatine process of maxilla Condylar process of mandible Coronoid process of mandible Alveolar process of mandible Spinous process of vertebra TERM PRONUNCIATION DESCRIPTION/TRANSLATION Process (continued) EXAMPLES Transverse process of vertebra Superior articulating process of vertebra Inferior articulating process of vertebra Xiphoid process of sternum Coracoid process of scapula Styloid process of radius Coronoid process of ulna Styloid process of ulna Ramus of mandible Superior pubic ramus Inferior pubic ramus Frontal sinus Sphenoid sinus Ethmoid sinus Maxillary sinus Spine of scapula Spine of vertebra Anterior superior spine Anterior inferior spine Posterior superior spine Posterior inferior spine Ischial spine Ramus (pl., rami) RAY-mus (RAY-mye or RAY-mee) Curved portion of a bone, like a ram’s horn [literally branch] Sinus SYE-nus Cavity within a bone [literally hollow] Spine spyne Sharp, pointed process; similar to crested but raised more; for muscle attachment [literally thorn] Sulcus (pl., sulci) SUL-kus (SUL-kee or SUL-kye or SUL-sye) Groove or elongated depression [literally trench] Intertubercular sulcus Trochanter troh-KAN-ter or TROH-kan-ter Large bump for muscle attachment (larger than a tubercle or tuberosity) [literally runner] Greater trochanter of femur TOO-ber-kul Small tuberosity (see below); small oblong bump [tubercle is literally small bump or small lump] too-ber-AH-sih-tee Oblong, raised bump, usually for muscle attachment; also called a tuber; a small tuberosity is called a tubercle [tuber is literally bump or lump] Tubercle Tuberosity Radial sulcus Lesser trochanter of femur Tubercle of rib Greater tubercle of humerus Lesser tubercle of humerus Pubic tubercle Adductor tubercle of femur Frontal tuberosity Deltoid tuberosity of humerus Radial tuberosity Ischial tuberosity Tibial tuberosity NOTES: 1. Bone marking names are arranged alphabetically, not by location, structure, or function. 2. In Latin, modifiers follow the terms they describe. Thus, foramen magnum can be translated in exact parallel as “hole that is huge” but is best rendered as “huge hole.” 3. Literal translations of structure names may be helpful in locating them or remembering their shape or function. However, they are not necessarily accurate or complete descriptions of the structure. 4. Some alternate pronunciations are given here but many other pronunciations are possible. © Kevin Patton at lionden.com Rev. 20 SEP 13 For reuse, please contact permissions@lionden.com Some material adapted by permission from Anatomy & Physiology by Patton & Thibodeau (Mosby/Elsevier) 3
