Chapter 1 Flashcards
Anatomy is the study, classification, and description of
The structure and organs of the human body
Physiology is the science that deals with
The functions of the living organisms and it’s parts
Osteology
Study of bones
Arthrology
Study of joints
Axial skeleton
80 bones. Skull, ribs, vertebrae.
Appendicular skeleton
126 bones. Scapula, clavicle, arms, legs, pelvis
4 classifications of bones
Long, short, flat, and irregular
Long bones
Upper arm, forearm, femur, tib/fib
Short bones
Wrist, foot, carpals, tarsals
Irregular bones
Vertebrae
Flat bones
Skull, scapula, sternum
Functional joints, determined by mobility of joint
SAD
- synarthrosis
- amphiarthrosis
- diarthrosis
Structural joints
- fibrous joints
- cartilaginous joints
- synovial joints
Fibrous joints
- syndesmosis
- suture
- gomphosis
Cartilaginous joints
- symphysis
- synchondrosis
Synovial joints
Also have synovial capsule, different movement
Syndesmoses are fibrous articulations held together by
Interosseous ligaments. SLIGHTLY moveable. Little ligaments between bones. Amphiarthrodial
Sutures are immovable joints found in the
Skull; make ligaments make contacts with teeth like projections. Synarthroidal
Gomphosis have
Limited movement/teeth. Amphiarthrodial
Symphyses joints are a broad flattened disk of fibrocartilage
Between two bony surfaces. Pubic, intervertebral discs
Synchondrosis is a temporary joint where
Hyaline cartilage turns into bone. Long bones and growth plates have these
Synovial joints are freely moveable with a fibrous (joint) capsule, are generally
Diarthrodial. Mostly found in upper and lower limbs and reinforced by ligaments
Movements of synovial joints
- plane (gliding)
- ginglymus (hinge)
- pivot (trochoid)
- ellipsoid (condylar)
- saddle (sellar)
- ball & socket (spheroidal)
- bicondylar
Body habitus
- sthenic (most common)
- hyposthenic/asthenic
- hypersthenic (least common)
Axial (horizontal) plane is a
Transverse plane that divides the body into superior (top) and inferior (bottom) parts
Longitudinal sections
Sagittal, coronal, oblique
Base plane of the skull is a transverse plane connecting
The bottom of the orbit to the top of the EAM
Occlusal plane of the skull is a horizontal plane formed by the
Biting surface of the teeth with jaw closed
Anterior or ventral
AnVe- front half of patient in anatomical position
Posterior or dorsal
PoDo- back half of patient in anatomical position.
Dorsum pedis
Top of foot, anterior or ventral
Plantar surface of foot
Bottom of foot, posterior or dorsal
Radiographic positions
- PA
- AP
- PA oblique
- AP oblique
- mediolateral
- lateromedial
Mediolateral projection, CR enters the
Medial aspect and exits the lateral
Lateromedial projection, the CR enters the
Lateral aspect of the part and exits medially
Supine
Laying on back, facing upwards
Prone
Laying on abdomen facing downwards
Erect
Upright to stand or sit erect
Recumbent
Lying down in any position.
- dorsal recumbent (supine)
- ventral recumbent (prone)
- lateral recumbent (lying on side)
Trendelenburg
Head lower than feet
Fowler
Head higher than feet
Sims
Recumbent oblique position. Patient on left anterior side, right knee flexed, left arm behind back
Lithotomy position
OBGYN stirrups
Lateral recumbent is labeled based on
Whatever side is on the table
Lateral position is a side view that is determined by the side
Closest to the IR, or which side the CR exits
Left or right posterior oblique positions of the torso (LPO or RPO)
Labeled by which side is closed to the IR
Left or right anterior oblique positions of torso (LAO or RAO)
Labeled based on which anterior part of the body is facing/closest to the IR
Decubitus
Body on horizontal surface and CR is horizontal
Right or left lateral decub is labeled by
Side down. CR can enter AP or PA
Dorsal decub
Lying on the back, L or R lateral labeled by side closest to IR
Ventral decub
Lying on stomach, L or R lateral labeled by side closest to IR
Axial projection
Inferosuperior axial projection and superoinferior axial projection
Tangential projection, CR touches a curve/surface only at one point and
Demonstrates part of anatomy without superimposition of another part of anatomy
Cephalad (cephalic)
Towards the head
Caudad (caudal)
Towards the feet
Internal (interior)
Nearer to the center
External (exterior)
Away from the center
Superficial
Nearer the skin surface
Deep
Away from skin, father into the body
Ipsilateral
Same side of body
Contralateral
Opposite side of body
Flexion
Decreases angle of a joint
Extension
Straightening of a joint
Ulnar deviation
Turn/bend the hand/wrist towards ulnar side
Radial deviation
Turn/bend hand/wrist towards the radial side
Dorsiflexion
Decrease the angle at the top of the foot. Toes pointing to the sky
Plantar flexion
Extend joint ankle.
Eversion
Outward stress movement of the foot at the ankle joint
Inversion
Inward stress movement of the ankle without rotation of the foot
Valgus
Abnormal position of a body part away from the midline of the body
Varus
Abnormal position of a body part forced towards the midline of the body
Internal (medial) rotation
Turning of anterior body part towards the medial plane
External (lateral) rotation
Anterior part away from medial plane
Abduction
Movement of arm or leg away from midline of the body
Adduction
Movement of arm or leg towards the midline of the body
Rotation turns/rotates the body part on its axis but tilt is a slanting
Movement with respect to the long axis
Position indicates patients general physical position and
Specific body positions such as oblique and lateral
Projection is the correct positioning term that describes or refers to a path or
Direction of the CR, projecting the image onto the IR
View is the discussion of a
Radiograph or image (not a correct positioning term)
Images should have these 2 markers minimum
- patient identification & date
- anatomical side marker
Minimum of 3 projections when imaging joints
- usually AP or PA, oblique, or lateral
- due to multiple surfaces & angles of the bones of the joint
Topographic landmarks are bony projections of the body that a radiographer must
Palpate to determine where organs and structures of the body are located
Palpation
Applying light pressure to the patient with fingertips, always inform patient and why
Portrait

Crosswise
Decub images are placed
Horizontally with the patients side up facing up
