Transcript of Anatomy

Anatomy and Physiology
Objective:
To understand how Anatomy and Asana join to create a safe yoga practice

Success Criteria:

I will understand:
the Importance of Anatomy and how it pertains to yoga

Why joint stability and optimal alignment are so important

http://yogadork.com/2014/02/17/awesome-x-ray-video-shows-beautiful-view-of-yoga-from-within/

Frontal/Coronal:
divides body front to back

Sagittal:
divides body into Left and right


Transverse:
divides body into top and bottom
Planes of Motion
postures?!
What are the applications to yoga?
Anatomical Structures
There are Three main anatomical groups in the body:
Bones - regrow
hypervascular
(osseous tissue)

Cartilage - do not regrow hypovascular
(cartilaginous tissue)

Joints - hypovascular
link between 2 bones/bones to cartilage
=> ligaments

1. Skeletal
Where are the joints in your body?
Muscles:
origin, insertion, action(vascular)

Tendons:
attach muscles to bones (avascular)

Fascia:
Webbing
Adhesions
2. Muscular
Why do we need to know this?
Nervous Tissue

BrainS!!!
Neurons

Autonomic Nervous System
1. Sympathetic "fight, flight, fright"
2. Parasympathetic
"rest and digest"


3. Neuromuscular
Muscle Contractions
Agonist and Antagonist
Why are we learning about this?

What poses have agonist vs. antagonist?

What poses are eccentric vs. concentric?

what poses are isometric vs. isotonic?
Applications to Yoga?!
Warming body.

Balancing body.

Ensuring safety.
Application to Yoga?
Ankle, Knee and Pelvic Chain
Abdomen
Muscular barriers

Top most: Diaphragm
Bottom most: Pelvic Diaphragm
Three layers:
1. Rectus
2. Obliques (external, internal)
3. Transversus

Muscular lock
Voluntary and involuntary actions
Support in postures
Movements to strengthen and stretch

duh duh duh....Pesky Psoas!!!!
Scapular Stability
Stabilize the scapula against the ribcage

Spine
Divided into 4 segments
1. Cervical (7)
2. Thoracic (12) - ribs?!
3. Lumbar (5)
4. Sacral (1 ~ 5 fused)
[Also a coccyx - but that's vestigial]
Importance of Anatomy
1. Alignment:
What holds up on standing postures?
Muscles move bones, joints stack.

2. Efficiency of Movement:
proper alignment, proper engagement of muscles

3. Physiological Effects of Yoga:
Why do we do yoga?
What efffects do we feel during and after the class?
Blood. (circulatory system)
Function?
Two types of Blood Vessels
How much blood in Human body compared with what your Cardiac Output could be.

Lymph. (lymphatic system)
Function?
One way system, but no valves
Enters blood stream at subclavian veins
Sub Group:
Fluid Connective Tissue
Skeletal Muscle
Primary interest

Smooth Muscle
Myogenic control mechanism

Cardiac Muscle
Heart beat (two cardiac cells beat like one!)
Three types of muscle
Types of action:
1. Isometric
2. Isotonic
A. Concentric
B. Eccentric
Intervertebral Disks
- Jelly donut

Functions of Spine?

Areas of most & least mobility in spine?
Motions of the spine
Forward Flexion and Extension
Lateral Flexion and Extension
Twisting/Rotation
Rectus
Abdominus
Internal Obliques
Transversus Abdominus
building to motion
Ankle: is a joint - movement between Talus and Tibia

Knee: is a joint between the femur and Tibia = it is a way station for force transmission
- Structures of the knee

Hip: major weight bearing joint between pelvis and femur bone.
- Opposites React!
Why is learning about the foot knee and pelvis important?

Where can we use this in yoga?

PSOAS!!


Applications to Yoga
Joints are most susceptible to injury.

Why?

How can we protect our Joints?


Joint Stability

Muscles involved:
Rhomboids
Serratus Anterior
Trapezius
Levator Scapulae
Pectoralis Minor
Rotator Cuff:
SITS
Supraspinatus
Infraspinatus
Teres Minor
Subscapularis
Arm and Shoulder Joint
Muscles of stability but not power
INJURY FREE IS THE WAY TO BE!!!
Why do we breath?

How do we breath?

What does breathing do?

Belly vs. chest breathing
- bad habits and injuries
BREATHE!
Where can you use this in your asana practice?
Bones?

Arm movement and at wrist (flexion, extension vs. supination,pronation)

Most stable joint in hand?


Arm and Hand
Hyper extension of elbow
Hyperextension of the Knee
Optimal Alignment
What does this mean to you?

Lets everything together and break down a few postures.
How can we cue it?!
How does this fit with planes of motion?
