UNIT 1 (MODULE 1) LABORATORY 1 Flashcards
What is Anatomical Reference System?
are the terms used to describe direction, position, and location of the body
What are the 4 Anatomical References?
- Anatomical Direction
- Anatomical Planes and Axes
- Body Cavities (Quadrants and Regions)
- Structural Units
What is Anatomical Direction?
- are terms that are used to describe the position of the body
- some anatomical directions form axes and planes
What are the 14 Anatomical Directions?
Superior, Inferior, Anterior, Posterior, Medial, Lateral, Proximal, Distal, Internal, External, Superficial, Deep, Central, and Peripheral
What is Superior?
uppermost or above
What is Inferior?
lowermost or below
What is Anterior?
towards the front
What is Posterior?
towards the back
What is the other term for Superior?
Cephalad
What is the other term for Inferior?
Caudal (occasionally)
What is the other term for Anterior?
Ventral
What is the other term for Posterior?
Dorsal
What is the meaning of Caudal?
towards the tail
What is the meaning of Ventral?
belly side
What is the meaning of Dorsal?
backside
What is Superior in Biped Animals like humans?
uppermost
What is Inferior in Biped Animals like humans?
lowermost
What is Anterior in Biped Animals like humans?
towards the front/belly side
What is Posterior in Biped Animals like humans?
towards the back/ backside
What is Superior in Quadruped Animals?
Dorsal/ backside
What is Inferior in Quadruped Animals?
Ventral/ belly side and feet
What is Anterior in Quadruped Animals?
Cephalad/ towards the head
What is Posterior in Quadruped Animals?
Caudal/ towards the tail
What is Medial?
towards or nearest the midline
What is Lateral?
towards the side or away from the midline
What is Proximal?
near the point of attachment or origin
What is Distal?
away from the point of attachment or origin
What are Internal and External?
are terms that are used to describe in reference with the central axis or longitudinal axis
What are Superficial and Deep?
are terms that are used to describe in reference with the body surfaces
What is Internal?
within or interior to
towards the central axis
What is External?
outside or exterior to
away from the central axis
What is Superficial?
towards the surface of the body
What is Deep?
away from the surface of the body
interior to the body
What is Central?
main part
What is Peripheral?
extending to the main part
What is Anatomical Planes?
are imaginary flat geometric surfaces that are useful in describing the dissection of an organ or the body as a whole
What are the different types of Anatomical Planes?
Frontal/Coronal Plane, Sagittal Plane, and Transverse Plane
Obliques (Sometimes)
What is Frontal Plane?
are planes right angle to sagittal planes dividing or separating into anterior and posterior portions
What is the other term for Frontal Plane?
Coronal Plane
What is Sagittal Plane?
are planes that divide the body into right and left portions
What are the 2 types of Sagittal Plane?
Parasagittal plane and Midsagittal plane
What is the Parasagittal plane?
a type of sagittal plane that divides the body into unequal right and left portions
What is the Midsagittal plane?
a type of sagittal plane that divides the body into equal right and left portions
What is a Transverse plane?
are planes that divide the body into superior and inferior portions
What are the terms used in describing the internal structures of organs?
Cross-section and Longitudinal Section
What is a Cross-section?
a transverse section that divides or separate right angle to a long axis
What is a Longitudinal section?
a sagittal section that divides or separate vertically to a long axis
What are Axes?
are the movements made in a plane
What are the different types of Axes?
Frontal/ Sagittal Axis, Antero-posterior axis, and Craniocaudal or Longitudinal Axis
What is a Frontal/ Sagittal Axis?
a line that runs from the right to the left through the centre of the body
What is a Antero-posterior Axis?
a line that runs from the front to back through the centre of the body
What is a Craniocaudal or Longitudinal Axis?
a line that runs from the upper to lower through the centre of the body
What plane formed Frontal/ Sagittal Axis?
Sagittal plane
What plane formed Anteroposterior Axis?
Transverse plane
What plane formed Craniocaudal or Longitudinal Axis?
Frontal plane
What direction formed Frontal/ Sagittal Axis?
Medial and Lateral direction
What direction formed Anteroposterior Axis?
Anterior and Posterior direction
what direction formed the Craniocaudal / Longitudinal axis?
Superior and Inferior direction
What are Body Cavities?
contains the organs included in maintaining homeostasis
What are the 2 types of Body Cavities?
Dorsal and Ventral Cavity
What are the subdivisions of the Dorsal cavity?
Thoracic cavity and Abdominal cavity
What are the subdivisions of the Ventral cavity?
Cranial cavity and Spinal cavity
