Week 6

Arm 1 bone

Forearm 2 bones

Phalanges 14 bones

Carpals 2 rows of 4 = 8

Metacarpal 5 bones

Humerus

            Articulates with glenoid cavity at the proximal end

            Articulates with both Radius and Ulna distally

Ulna

            Medially fits in olecranon fossa via olecrannon process

            Articulates with carpals distally

Radius

            lateral side of the elbow to the thumb side of the wrist

            articulates with the capitulum of the humerus, the radial notch and the head of the           ulna.

Pelvic Girdle

            2 innomimal bones

            os coxae

            cotal bones

            Each hip bone has Fused 3 parts

                        Ilium – Top broad flat part

                        Ischium – inferior and posterior part

                        Pubis – Ventral anterior forming pubic arch

            Acetabulum

                        Articulates with femur

            Obturator foramen

                        Filled with connective tissue

            Pubic Symphysis

                        Firm union with hyaline & fibrocartilage

Thigh

            Femur

                        Largest and heaviest bone in the body

                        Articulates with acetabulum via the trochanter

                        Distal end expands for articulation with tibia

                        Has medial and lateral condyles

Tibia

            Medial

            Weight bearing

            Tibial tuberosity

            Distally articulates with talus

Fibula

            Lateral

            Proximal articulation with tibia

            Distal articulation with talus

Foot

            Calcaneous

            Talus

            I  - II – III  cuniforms

            Cuboid

            Metatarsal medial à lateral

                        Same name of phalanges

                        Some distal and middle phalanges have been known to fuse

Patella

            Sesamoid

            Entirely within a tendon at a point of major pressure

                        Patellar tendon

Arthrology

            3 categories based on movement

                        Synarthoris à no movement

                        Amphiarthrosis à some movement

                        Diarthrosis à freely moveable

            3 based on structure

                        Fibrous à little to no movement

                                    Syndesmosis - more fibrous tissue

                                    Suture - minimal fibrous tissue

                        Cartilage à litte to no movement

                                    Synchondrosis – temporary growth plate

                                    Symphysis

                        Synovial à freely moveable

                                     Joint capsule line with synovial membrane for synovial fluid                                           production for lubrication

                                    Synostosis – sutures that have completely calcified

                                    Arthrodia – Gliding joints

                                                Carpal bones

                                                Non axial
