The 11 Systems of the body?
- Integumentary (skin)
- Skeletal
- Nervous
- Cardiovascular
- Endocrine (glands/hormones)
- Muscular
- Respiratory
- Reproductive
- Digestive
- Urinary
- Lymph/Immune
anatomical position?
Mountain pose with palms forward
Axial
head, neck, and trunk
Appendicular
limbs/extremities
Anterior
towards the front
Posterior
towards the back
Distal
away from the trunk toward the fingers and toes
Proximal
towards the trunk away from the fingers and toes
Superficial
Towards the skin or outside
Deep
towards the inside or away from the skin
superior
up, Towards the top of the head
inferior
down or below, towards the feet
medial
towards the midline
lateral
away from the midline
flexion
A movement in a sagittal plane which takes a part of
the body forward from anatomical position.
Exceptions: knee flexion, dorsiflexion\
Extension
A movement in the sagittal plane which takes a part of
the body backward from anatomical position. Except:
knee extension and plantar flexion
abduction
A movement in a frontal plane which takes a
part of the body away from the median plane.
Adduction
A movement in a frontal plane which takes a
part of the body toward the median plane.
(Add it to your body- it comes “in” to you) (Second ½ of jumping jack)
Pronation
Hand faces back, opposite
anatomical position.
Supination
Hand faces forward
same as anatomical position.
Dorsiflexion
“flexing” the foot
Plantar Flexion
pointing the toes
Lateral Flexion or Side Bending
Axial spine motion in the frontal plane away
from anatomical position.
Function of the Skeletal System
Support: Structural Support for the entire body
Protection: Surrounds soft tissue- critical organs
Movement: Creates the levers for muscles to attach to and
move the body.
Mineral Homeostasis: Stores minerals and fats. Releases
calcium and phosphorus as needed.
Blood Cell Production: Bone Marrow produces red and
white blood cells.
What is a joint
The Junction or Union of two or more Bones in the Body.
Primary Function is to provide motion and flexibility to the body
frame.
Synarthrosis
joint
Essentially NO motion/Fibrous
Skull, Teeth
Ball and socket joints
Flexion, Extension, Abduction, Adduction,
Internal, and External Rotation
only joint that moves in all directions
Hip and Shoulder
function of a Synovial Joint
Joint designed for Motion
Joint Motion: Spreads fluid around keeping joint healthy and lubricated.
Motion is Lotion
Synovial Membrane
Releases Synovial Fluid
Synovial Fluid
Bathes joint with nutrients
Joint Capsule
Ligaments to provide joint stability
Cartilage
Protects the ends of bones and helps with smooth motion
Ellipsoid
Flexion, Extension, Abduction, Adduction
Wrist, Fingers
Saddle
Flexion, Extension, Abduction, Adduction
Thumb
Hinge
Flexion and Extension
Knee and Elbow
Pivot
Rotation
Head C1C2, Forearm
Gliding/ Plane
Flat Edges Meet
Up, Down, Left, Right Diagonally
How to protect the joints
Proper Warm-up
Engage your Muscles
Motion is Lotion
Alignment
Avoid Pushing Joint into End Ranges
balance Between Muscle Groups
Amphiarthrosis
joint
Slight/Minimal Motion, Connected by Cartilage or
Ligaments
Pubic, Vertebral Column
Diarthrosis
Synovial Joint,
Moves Freely
Shoulder, Hip, Knee, Elbow, Wrist, Ankle, etc
