Lecture 29 Intro To Vertebrate Anatomy Flashcards
Two types of anatomy are
-gross
-histology
Two approaches to anatomy
-functional
-regional
Functional Approach to anatomy is
Based on functional systems (ie. respiratory, nervous, circulatory, etc)
Regional Approach to anatomy is
The anatomy of specific regions including all structures
Four anatomical planes are
-median
-dorsal
-sagittal
-transverse
Median anatomical plane
Equal left and right halves (ie. middle)
Transverse Anatomical Plane
-cross section of body (infinite planes)
Sagittal Anatomical Plane
Parallel to median plane but from any distance to the middle (ie. infinite planes)
Dorsal Anatomical Plane
Not commonly used, split in half (ie. dorsal and ventral)
Towards the back
Dorsal
Towards the stomach
Ventral
Away from body
Distal
Towards the body
Proximal
Towards the head
Cranial
Towards the tail
Caudal
Towards the nose
Rostral
Top of foot
Dorsal
Bottom surface of foot (front AND back)
Palmar: front foot
Plantar: back foot
Towards middle of the body
Medial
Furthest from middle of the body
Lateral
Same side of body
Ipsilateral
Opposite sides of body
Contralateral
What anatomical terms are commonly used when referring to the Central Nervous System
-ipsilateral (same side of body)
-contralateral (opposite sides of body)
Long axis of the foot is
Between digits 3 and 4
How many digits in the paw
5 with 1 being the dew claw
Towards long axis
Axial
Away from long axis
Abaxial
Between the digits, the anatomical terms used are
-axial (towards long axis)
-abaxial (away from long axis)
Superficial
Closer to the surface of body (usually skin)
Deep
Away from surface of body, closer to organs/tissues
Parietal is associated with the
Body wall
Visceral refers to
Organs within the thoracic and abdominal cavities
Pleura membrane lines
Thoracic wall
Supra-
Above
Infra-
Below
Digit 1 is always
Medial
Flexion
Decrease angle of joint
Extension
Increasing angle of joint to 180 degrees
Flexion and extension refer to ___ and not ____
The joint; entire limb
Protraction
Moving whole limb forward/cranially
Retraction
Moving whole limb backward/caudally
Pronation and supination refer to the
Palm
Which species has no supination
Horses
Pronation
Palm down
Supination
Palm up
Abduction
Movement away from the median plane
Adduction
Movement toward the median plane
