Yoga Anatomy Flashcards
The 11 biological systems in the human body
- Cardiovascular/Circulatory
- Digestive/Excretory
- Endocrine
- Integumentary/Exocrine
- Lymphatic/Immune
- Renal/Urinary
- Reproductive
- Respiratory
- Nervous
- Skeletal
- Muscular
Number of bones in the Appendicular System
126
Number of bones in the Axial Skeleton
80
Components of the Appendicular Skeleton
Pelvic girdle, lower limbs, pectoral girdle, upper limbs
Components of the Axial skeleton
Vertebral column, rib cage, sternum, skull, hyoid
Function of the Appendicular skeleton
~Walking, running and other movement
~Protect the major organs responsible for digestion, excretion and reproduction
Function of the Axial Skeleton
Transmits weight from the head, trunk and upper extremities down to the lower extremities at the hip joints. Therefore helps maintain upright posture
5 Types of Bones
- Flat Bone
- Irregular Bone
- Sesamoid Bone
- Long Bone
- Short Bone
Types of Joints
- Synarthrosis Joints
- Amphiarthrosis Joints
- Synovial Joints
5 Types of Synovial Joints
- Ball and Socket
- Hinge
- Gliding
- Pivot
- Saddle
The 3 Joints of the Pelvis
- Sacroiliac Joint (SI Joint)
- Acetabulofemoral Joint
- Public Symphysis
Ligaments of the elbow
- Annular ligaments
2. Medial collateral ligament
3 Types of Muscles
- Skeletal
- Cardiac
- Smooth/Visceral
7 Muscle Shapes
- Bipennate
- Multipennate
- Parallel fusiform
- Parallel
- Unipennate
- Convergent
- Circular
4 Characteristics of Skeletal Muscle
- Contractility (can shorten up to 2/3)
- Extensibility (can extend 1.5 times its length)
- Excitability (can receive abd respond to stimulus)
- Elasticity (can return to original shape and length)
5 Sections of the Spine
- Cervical (lordosis)
- Thoracic (kyphosis)
- Lumbar (lordosis)
- Sacral (kyphosis)
- Coccyx
Number of Skeletal muscles in the human body (estimate)
Over 600
11 Functions of muscle (all types)
- Move bones (to move body)
- Generate heat
- Protect underlying structures of the body
- Maintain posture
- Circulate blood throughout the body
- Controls heartbeat
- Controls breathing
- Controls digestion
- Controls vision
- Controls urination
- Controls childbirth
4 Characteristics of Skeletal Muscle
- Generally attached to bones
- Creates movement at joints
- Striated appearance
- Under voluntary control
3 Characteristics of Cardiac Muscle
- Located at the heart
- Striated appearance
- Involuntary action
3 Characteristics of Visceral/Smooth Muscle
- Located in the blood vessels, airways and Visceral organs
- Not striated
- Involuntary action
Skeletal Muscle Anatomy (4 subsections)
- Muscle tissue is made up of bundles of fascicles
- Fascicles are made up of muscle fibres
- Muscle fibres are made of myofibrils
- Myofibrils are made of thick and thin filaments
4a - Filaments = twisted strands of molecules that create contractions
- Each bundle in each stage is surrounded by connective tissue which come together at the end to create tendons and ligaments
Define agonists
Muscles that initiate joint action of each other
Define antagonists
Muscles that oppose the joint action of each other (eg biceps and triceps)
Define synergist
- Muscles that support and modulate the agonist-antagonist dynamic
- Minimise excessive movement at the joint
- Stabilise one part of the body to support the movement in another part
Define Fixator
- Supports and protects the joint
2. Initiates precision of movement
Define monoarticular muscle
- Crosses only one joint
- Support articulation and discrimination at each joint
- Essential for alignment of each joint
Define Polyarticular Muscles
- Crosses two or more joints
- Integrate the limbs into the torso
- Help us transfer weight effectively
- Coordinate sophisticated shape changes in torso
- Muscles in the hands and feet cross 9 joints
- Spinal muscles cross 12-15 joints
- Diaphragm crosses over 100 joints
2 Types of isotonic contractions
- Concentric
2. Eccentric
2 Main types of Muscular contractions
- Isometric (holding)
- Isotonic (moving)
2a) Concentric: muscle fibres shorten (eg bicep curl towards body)
2b) Eccentric: muscle fibres lengthen (eg bicep curl away from body)
Define Origin of muscle
Where muscle starts
Define Insertion of Muscle
Where muscle ends
4 Types of Stretching
- Active Static Stretching (Contract the antagonist muscle to signal the target muscle to relax. Eg engage quads in a forward fold)
- Passive Stretch (Relax into a stretch using only the force of the body weight to stretch muscles)
- Facilitated Stretching (Contracting the muscle being stretched during an active static stretch)
- Dynamic Stretching (Repetitive movements of the body into increasingly deeper stretches)
