Osteology: structure of bones
|
|
Skeleton that gives form to the body is made up of bone and cartilage (specialised connective tissue). Bone is stronger than reinforced concrete.
Regional from one region e.g. thorax
Axial skull, vertebrae, sternum and ribs (primary)
Appendicular of limbs
Shape:
Long in limbs, have medullary cavity e.g. metacarpals, phalanges
Short e.g. carpals and tarsals
Flat skull bones, scapulae
Sesamoid contained within tendon of muscles e.g. patella
Accessary additional e.g sutural bones (generally in lambdoid sututre)
Irregular not the above e.g. vertebrae
|
|
Elevations:
Tubercle/tuberosity small bump on humerus (trochanter large bump on femur)
External occipital protuberance on outside of occipital bone
Spinous process - thorn like short projection
Crest/Ridge - e.g. iliac crest
|
|
Depressions
Fossa trench or ditch, depression e.g. infraspinous fossa
Sulcus any long groove or furrow e.g.intertubercular sulcus
Notch an indentation
Foramen an aperture/hole/perforation in bone or membrane e.g.f.magnum
Canal a tube/duct/channel (both ends open)
Meatus a tube with one end closed e.g. external auditory meatus
|
|
Joints Classification based on substance uniting two or more bones
Fibrous e.g. sutures, tibiofibular joint
Cartilagenous e.g. intervertebral
Synovial commonest, most mobile e.g. shoulder joint
|
|
Scapula
Costal Surface coracoid (crooked finger) process, superior, lateral and medial borders
|
|
Dorsal Surface spinous process and its lateral flattened part acromion, supra and infra spinous fossa
|
|
Lateral Aspect glenoid cavity/fossa for articulating with the humeral head
|
|
Humerus
Proximal (anterior) head, tubercles and intertubercular groove
|
|
Distal (anterior) trochlea (pulley) is medial and articulates with ulna, capitulum is lateral condyle joins with radius, medial condyle is larger and palpable
|
|
Distal (posterior) olecranon fossa for similar named process of ulna
|
|
Radius and Ulna
Olecranon process of ulna and head of radius, styloid process of radius and ulna
What would you call a membrane connecting the two bones?
(Answer on next image interosseous membrane)
|
|
Hand
Phalanges 3 in each finger but 2 in thumb
Metacarpals 5 in region of palm (knuckles formed by their heads)
Carpals 8 bones arranged in two rows
|
|
Hipbone (lateral aspect)
Formed by ilium, ischium and pubis
Sit on ischial tuberosity
All 3 take part in formation of acetabulum
ASIS = anterior superior iliac spine is palpable
|
|
Hipbone (medial aspect)
Obturator foramen is covered by a membrane
Iliac fossa is filled by iliacus muscle
Greater sciatic notch is formed by ilium and ischium
|
|
Pelvis
Bony pelvis formed by two hip bones and sacrum
Pelvis means basin
Bottom formed by pelvic diaphragm
|
|
Femur
Largest bone,
|
|
Distal
|
|
Femur (proximal part)
Head fits in acetabulum to form hip joint
Neck often fractured in elderly
Two large projections are trochanters
|
|
Medial condyle is larger than lateral
At end of condyle is epicondyle
|
|
Tibia and Fibula
Correspond to radius and ulna
Connected by interosseous membrane
Distal ends form bumps of ankles malleoli
|
|
Tibia and fibula proximal part
Tibial tuberosity gives attachment to quadriceps tendon
|
|
Tibia and fibula (distal)
Note grooves for articulation with talus
|
|
Vertebrae 1
Cervical 7, small body
Thoracic 12, ribs attached here
|
|
Vertebrae 2
Lumbar -5, large body for weight bearing
Sacral 5, fused by 20-25 years
|
|
Sacrum
Sacral foramina are for nerves and blood vessels
(correspond to intervertebral foramina)
|
|
Sternum
Manubrium joins with body at sternal angle (vertebral level T4)
|
|
Ribs
12 pairs of ribs attached to thoracic vertebrae
1-7 articulate with sternum in front true ribs
8-10 articulate with cartilage of preceding rib false ribs
11 12 anterior ends are free floating ribs
