Intro to MSK Flashcards
Define Human Anatomy
the study of the structure of the human body and the relation of its parts
Define the 3 types of Anatomy:
- Gross Anatomy
- Histology
- Cytology
- Gross Anatomy: Macroscopic Anatomy
- Histology: Microscopic Anatomy
- Cytology: Cell Biology
Regional vs. Systemic Anatomy
Regional is by region of the body, while systemic is moving through the systems (ex. osteology, arthrology, etc)
Osteology
Study of Skeletal System
Chondrology
Study of Cartilage
Arthrology
Study of Joints and Ligaments
Myology
Study of Skeletal Muscles
Pulmonology
Study of Lungs and Airways
Cardiology
Study of the Heart
Dermatology
Study of the Integumentary System (Skin)
Gastroenterology
Study of Digestive and Accessory Digestive
Systems
Urology
Study of the Urinary System
Endocrinology
Study of the Endocrine System
Gynecology
Study of the Female Reproductive and Genital Systems
Andrology
Study of the Male Reproductive and Genital Systems
Angiology
Study of the Circulatory System
Neurology
Study of the Nervous System
Anatomical Position
- Standing erect
- Head and Eyes directed forward
- Upper Extremities at the side 4. Palmar surface of hands directed forward
- Lower Extremities together 6. Toes directed forward
Sagittal
“Straight thru;” Runs from the front to back, parallel to the long axis
Coronal
Frontal; Runs side to side, parallel to the long axis
Transverse
Horizontal; Cuts body into upper and lower; Perpendicular to the long axis
Midsagittal (median plane)
Runs front to back in the midline, parallel to the long axis
Oblique
Every other plane other than the main ones (no proper placement)
Dexter
Right
Sinister
Left
Anterior
Front (Ventral)
Posterior
Back (Dorsal)
Superior
Up (Cranial)
Inferior
Down (Caudal)
Medial
Toward the Midline
Lateral
Away from the Midline
Median
In the Midline
Proximal
Nearer to a Reference Point
Distal
Farther from a Reference Point
Superficial
Nearer to the Surface
Deep
Farther away from the Surface
External
Outside
Internal
Inside
Ipsilateral
Same Side
Contralateral
Opposite Side
Supine
Lying on Back
Prone
Lying Face Down
Flexion
Decrease the Angle between two Structures or Bones, usually in the
Sagittal Plane
Dorsiflexion
Elevation of the foot at the Ankle
Plantarflexion
Directing the toes Inferiorly at the Ankle
Lateral Flexion
Decrease the Angle between a Midline structure and
the Lateral Surface of the Body, usually in the Coronal Plane
Extension
Increasing the Angle between two structures or Bones to the point of Hyperextension, usually in the Sagittal Plane
Abduction
Movement away from the Midline, usually in the Coronal Plane
Adduction
Movement toward the Midline, usually in the Coronal Plane
Medial Rotation
Rotation toward the Midline
Lateral Rotation
Rotation away from the Midline
Circumduction
Circular movement through a Spheroidal Joint
Protraction
Protrusion; To push out
Retraction
Retrusion; To pull in
Elevation
To lift up
Depression
To pull down
Inversion of the Foot
Direct the Plantar Surface Medially
Eversion of the Foot:
Direct the Plantar Surface Laterally
Supination of the Forearm
Direct the Palmar Surface Anteriorly
Pronation of the Forearm
Direct the Palmar Surface Posteriorly
Opposition
Touching Thumb to 5th Digit
Reposition
Returning from Opposed position (opposition) to Anatomical Position
2 Examples of long bones
Humerus/ Femur
2 Examples of short bones
Tarsals/ Carpals, cuboidal in shape
Flat Bones
Squamous Skull, designed to protect the brain
Irregular Bones
Facial Bones, not long, short or flat
Sesamoid Bones
Patella, embedded in tendon
Sutural/Wormian Bones
Amid Skull Sutures in the Neurocranium
Epiphysis
portion of a bone furthest from the center
Epiphyseal Plate
Cartilaginous region between Epiphysis and
Metaphysis
Where does Secondary Ossification Center occur?
Epiphyseal Plate
Metaphysis
flared region between Diaphysis and Epiphyseal Plate
Diaphysis (central portion of a bone, Primary Ossification Center)
Central portion of a bone
Where does the Primary Ossification Center occur?
Diaphysis
Epiphyseal Line
Region between Metaphysis and Epiphysis after cessation
of Ossification
Compact Bone
Outermost solid layer
Cancellous/ Spongy Bone
Innermost sinusoidal layer
Medullary/ Marrow Cavity
Replaces some of the Cancellous Bone Layer in
adults
