Q

Regional Anatomy🫀🫁🧠

A

Regional anatomy (topographical anatomy) considers the organization of the human body as major parts or segments.
Head
Neck
Trunk

Q

Anatomical position

A

The anatomical position is the standard reference position of the body used to describe the location of structures

Characteristics of anatomic position:
- head, eyes (gaze), and toes directed anteriorly
- upper limbs by the sides with the palm facing interiorly
- lower limbs close together with the feet parallel in the toes directly

24
Anatomical sections
The main use of anatomic plants to describe sections
24
Frontal (coronal) planes
Are vertical planes dividing the body into anterior (front) and posterior (back) parts
25
Transverse planes
Are horizontal planes dividing the body into superior (upper) and inferior (lower) parts Note: radiologist referred to transverse plan as transaxial, which is commonly shortened to axial planes
26
Longitudinal sections
Run length ways or parallel to the long axis of the body Note: median, sagittal, and frontal plants are the standard longitudinal sections
27
Transverse section (cross section)
Our slices of the body, or its parts that are cut at right angles to the longitude of axis of the body, or of any of its parts
28
Oblique sections
Are slices of the body or any of its parts that are not cut along the previously listed anatomical planes
29
Superior Cranial
Upward or near the head Cranial: located toward the head
30
Inferior Caudal
- Downward, or near the feet - Located toward the tail
31
Posterior What is a synonym for posterior?
- the back service of the body or near to the back - synonym: dorsal
32
- Anterior - What is a synonym? - __________ is often used instead of interior when describing parts of the brain
- located toward the front - ventral - Rostral
33
Medial
A structure that is near to the median plane of the body
34
Lateral
A structure that is farther away from the medium plane
35
Superficial
Situated near the surface
36
Intermediate
Between a superficial and a deep structure
37
Deep
Situated deep beneath the surface
38
External
Outside of or farther from the center of an organ or cavity
39
Internal
Inside or closer to the center, independent of direction
40
Proximal
Close to, or to the trunk or point of Origin
41
Distal
Away from the trunk or point of origin (toward the end of the limb)
42
Dorsal
Pertaining to the back of the hand or top of the foot
43
Palmar
Pertain to the palm of the hand
44
Planter
Pertain to the sole of the foot
45
Terms of laterality
- Bilateral - Unilateral - Ipsilateral - contralateral
46
Bilateral
Peered structures having right and left members
47
unilateral
On one side only
48
Ipsilateral
Occurring on the same side of the body as another structure
49
Contralateral
Occur on the opposite side of the body relative to another structure
50
Flexion
Bending, or decreasing the angle between the bones or parts of the body
51
Extension
Straightening, or increase in the angle between the bones or parts of the body extension usually occurs in a poster direction
52
Dorsiflexion
Describes flexion at the ankle joint, as occurs when walking, uphill, or lifting the front of the foot and toes off the ground
53
Planarflexion
Bends the foot and toes toward the ground, as when standing on your toes
54
Abduction
Moving away from the median plane
55
Adduction
Moving toward the median plane
56
Right and left lateral flexion (Lateral bending)
Our special forms of abduction for only the neck and trunk
57
Rotation
Rotation, medial rotation, and lateral rotation
58
Rotation
Turning or revolving part of the body around its longitudinal axis, such as turning one's head to face sideways
59
Medial rotation
Internal rotation: brings the interior surface of a limb closer to the median plane
60
Lateral rotation
External rotation: takes anterior surface away from the median plane
61
Supination
Is the opposite rotation movement, rotating the forearm laterally Memory: you can hold soup in the palm of your hand when the flexed forearm is supinated, but are prone (likely) to spill it if the forearm is then pronated!)
61
Pronation
Rotates the forearm medially
62
Circumduction
Is it circular movement that involves sequential flexion, abduction, extension, and adduction (or in the opposite order) in such a way that the distal end of the part moves in a circle
63
Opposition
Is the movement by which the pad of the first digit (thumb) is brought to another pad
64
Reposition
The movement of the first digit from the position of opposition back to the anatomical position
65
Protraction
Anterolateral movements of the scapula on the thoracic wall, causing the shoulder region to move anteriorly
66
Retraction
Posteromedial movements of the scapula and the thoracic wall, caused the shoulder region to move posteriorly
67
Elevation
Races or moves apart, superiorly, as an elevating, the shoulders, when shrugging, the upper eyelid, when opening the eye, or the tongue would push it up against the palate (roof of mouth)
68
Depression
Lowers or moves apart inferiorly, as in depressing the shoulders, when standing at ease, the upper eyelid, when closing the eye, pulling the tongue away from the palate.
69
Protrusion
An anteriorly (forward) movement as in protruding the mandible chin, lips, or tongue
70
Retrursion
Movement posteriorly (backward), as in retruding the mandible, lips, or tongue
71
Eversion
Moves the soul of the foot away from the medium plane, turning the sole laterally
72
Inversion
Move to soul of the foot toward the median plane (facing the sole medially)
