Anatomical Planes & Body Movements
Comprehensive Nursing Study Guide
Learning Objectives
By the end of this study session, you will:
- Master the three anatomical planes and their clinical significance
- Understand fundamental body movements and their applications
- Apply anatomical terminology in clinical scenarios
- Utilize memory techniques for long-term retention
Anatomical Position – Foundation
All anatomical descriptions are based on the anatomical position: person standing upright, facing forward, arms at sides with palms facing forward, feet parallel and flat on the ground. This standardized reference point ensures consistent communication in healthcare.

Anatomical Planes: The 3D Body Map
Coronal = Cuts front/back
Transverse = Tops and bottoms (superior/inferior)
1. Sagittal Plane (Vertical/Lateral Plane)
Definition & Orientation
The sagittal plane runs vertically from front to back, dividing the body into left and right portions. Think of it as slicing the body like a book page – separating left from right.
Two Types of Sagittal Planes:
- Midsagittal (Median): Divides body into equal left and right halves
- Parasagittal: Any sagittal plane that doesn’t pass through midline
Clinical Applications
- • CT and MRI sagittal views for spinal assessment
- • Lateral X-rays of chest and abdomen
- • Brain imaging for midline shift evaluation
- • Surgical planning for lateral approaches
Movements in Sagittal Plane:
2. Coronal Plane (Frontal/Oblique Plane)
Definition & Orientation
The coronal plane runs vertically from side to side, dividing the body into anterior (front) and posterior (back) portions. Imagine cutting the body like slicing bread – front from back.
Memory Tip:
“Coronal” relates to “crown” – think of a crown sitting on your head from ear to ear, that’s the direction this plane cuts through your body!
Clinical Applications
- • Chest X-rays (AP and PA views)
- • Abdominal imaging for organ assessment
- • Cardiac catheterization positioning
- • Orthopedic evaluation of joint alignment
Movements in Coronal Plane:
3. Transverse Plane (Axial/Horizontal Plane)
Definition & Orientation
The transverse plane runs horizontally, dividing the body into superior (upper) and inferior (lower) portions. Think of cutting the body like slicing a cake into layers.
Alternative Names:
- Axial Plane: Used primarily in medical imaging
- Horizontal Plane: Describes the orientation
- Cross-sectional Plane: Shows body in cross-section
Clinical Applications
- • CT scan axial views (most common)
- • Cross-sectional anatomy study
- • Surgical planning for horizontal approaches
- • Assessment of organ levels and relationships
Movements in Transverse Plane:

Sagittal Movements
- • Flexion/Extension
- • Forward/Backward bending
Coronal Movements
- • Abduction/Adduction
- • Side-to-side movements
Transverse Movements
- • Rotational movements
- • Twisting motions
Body Movements: Dynamic Anatomy
Abduction Adduction = Away Across
Supination Pronation = Soup bowl Pour out
Flexion
Definition: Decreasing the angle between two body parts
Examples:
- Bending elbow (bicep curl)
- Bringing knee to chest
- Nodding head forward
- Bending wrist downward
Memory Tip: “Flex to make smaller”
Extension
Definition: Increasing the angle between two body parts
Examples:
- Straightening bent elbow
- Standing up from sitting
- Tilting head backward
- Straightening knee
Memory Tip: “Extend to make bigger”
Abduction
Definition: Moving a limb away from the body’s midline
Examples:
- Raising arms to the side (jumping jacks)
- Moving leg out to the side
- Spreading fingers apart
- Moving thumb away from palm
Memory Tip: “ABduction = Away from Body”
Adduction
Definition: Moving a limb toward the body’s midline
Examples:
- Bringing arms back to sides
- Moving leg toward midline
- Bringing fingers together
- Moving thumb toward palm
Memory Tip: “ADduction = ADd to the body”
Medial Rotation
Definition: Rotating a limb toward the body’s midline
Examples:
- Turning arm inward (palm faces back)
- Rotating thigh inward (pigeon-toed)
- Internal shoulder rotation
Memory Tip: “Medial = toward Middle”
Lateral Rotation
Definition: Rotating a limb away from the body’s midline
Examples:
- Turning arm outward (palm faces forward)
- Rotating thigh outward (duck-footed)
- External shoulder rotation
Memory Tip: “Lateral = away from center Line”
Inversion
Definition: Turning the sole of the foot inward (medially)
Examples:
- Rolling ankle inward
- Soles of feet face each other
- Common in ankle sprains
Memory Tip: “INversion = sole points IN”
Eversion
Definition: Turning the sole of the foot outward (laterally)
Examples:
- Rolling ankle outward
- Soles of feet face away from each other
- Less common injury mechanism
Memory Tip: “Eversion = sole points External”
Supination
Definition: Rotating forearm so palm faces upward
Examples:
- Turning palm up to hold soup bowl
- Receiving change from cashier
- Starting position for bicep curls
Memory Tip: “SUPination = holding SUP (soup) bowl”
Pronation
Definition: Rotating forearm so palm faces downward
Examples:
- Turning palm down to type on keyboard
- Pouring water from a pitcher
- Pushing down on a table
Memory Tip: “PRONation = palm PROne (down)”

Practice Questions & Self-Assessment
Question 1: Anatomical Planes
A patient is lying supine for a CT scan. The images show cross-sections from head to toe. Which anatomical plane is being visualized?
Question 2: Movement Analysis
A patient is performing a bicep curl. Identify the primary movement at the elbow joint and the plane in which it occurs.
Question 3: Clinical Scenario
A patient presents with difficulty turning their palm up to receive change. Which specific movement is impaired?
Question 4: Movement Terminology
During a physical therapy session, a patient is asked to move their arm away from their body to the side. What is this movement called?
Study Tips & Success Strategies
Memory Techniques
- Use your own body: Practice movements while studying to create muscle memory
- Create acronyms: Develop personal memory devices for movement sequences
- Visual associations: Link movements to everyday activities
- Teach others: Explain concepts to reinforce your understanding
