How does form and shape of bones reflect function
Form and shape reflect the function of the bone.
1-Long - leverage, support
2-Short - weight bearing

Tendon connects muscle to a bone
Origin - usually the most proximal place where tendon connects the muscle to the bone
Insertion - usually the most distal place where the tendon connects the muscle to the bone
What is a Ligament
Ligaments connects bone to bone
Limit the range of movement
What is Fascia
Fascia is a thin matrix of tissue - found all over the body - contributor to our health, well being and flexibility
What is a Joint
A joint is a specialised region where bones are connected by soft tissues, allowing range of motion to be safe as possible. Their shape reflect their function
What is a highly moveable joint called
Synovial Joint
1-Wherever bones come into contact with one another They are covered by hyaline cartilage
2-The areas between the bone ends are bathes in synovial fluid. There is no blood supply
3-Synovial membrane surrounds the space, the outside of a fluid filled balloon
4-Thick strong membrane surrounds this, called the joint capsule
Examples of synovial joints
1-Ball and socket (shoulder/hip) 2-Hinge (knee/elbow/finger) 3-Ellipsoid (radiocarpel) 4-Saddle (thumb) 5-Pivot(cervical vertebra 1-2) 6-Gliding (sacroiliac)
Agonists
A muscle that causes a movement
A muscle contracts to produce a certain action in a joint (muscle produces a movement against a load)
Agonists
1-A muscle that causes a movement
2-A muscle contracts to produce a certain action in a joint (muscle produces a movement against a load)
3- prime movers
Antagonist
1-A muscle that inhibits a movement
2-A muscle that relaxes while the agonist contracts - a muscle that opposes a movement against a load
3- Muscles that produce an opposing joint torque to the agonist muscles
What are the types of muscular contraction
Isotonic contraction
Concentric
Eccentric
Isometric contraction
No motion / movement (downward facing gog in holding phase)
what type of contraction is the downward facing dog in holding phase
Isometric contraction (no motion in the joint) - static
what type of contraction is the chaturanga

What is fascia
Fascia (latin) means band or bundle
1-Fascia is a soft tissue component of the connective tissue system
2-Surrounds and penetrates muscles, bones, organ, nerves and other structures in the body
3-Interconnected 3D web of tissue
4-Responsible for structural integrity, support, protection, shock absorption and sensory neurons
5-Essential for intercellular communication
6-Helps to guide the alignment of our blood vessels and nerves
7-It is the home for fat cells.
What are the 3 types of fascia
1-Superficial Fascia (lies just beneath the skin)
2-Deep Fascia (single 3D structure) envelops every muscle, organ connecting them all together and holding everything in place
3-Loose Fascia - intervening layer between deep and superficial fascia. Permits motion of slide and glide all over the body.
Locations on the body
Locations on the body:
Description of where structures lie in relation to certain landmarks
How many bones are there in the body
There are 206 named bones in the body.
What 2 groups are bones divided in
They are divided in two groups:
1-Axial: 80 (e.g. skull, spine, ribcage)
2-Appendicular: 126 (e.g. limbs)
What is muscle?

3-System of bio-mechanical regulation
What are the Anatomical Planes
1- Sagittal plane – a vertical line which divides the body into a left section and a right section.
2- Coronal plane / frontal – a vertical line which divides the body into a front (anterior) section and back (posterior) section.
3-Transverse plane – a horizontal line which divides the body into an upper (superior) section and a lower (inferior) section.
What is Inversion and Eversion
1-Inversion involves the movement of the sole towards the median plane – so that the sole faces in a medial direction.
2-Eversion involves the movement of the sole away from the median plane – so that the sole faces in a lateral direction.
What is Opposition and Reposition
A pair of movements that are limited to humans and some great apes, these terms apply to the additional movements that the hand and thumb can perform in these species.
1-Opposition brings the thumb and little finger together.
2-Reposition is a movement that moves the thumb and the little finger away from each other, effectively reversing opposition.
What is protraction and retraction
Protraction describes the anterolateral movement of the scapula on the thoracic wall that allows the shoulder to move anteriorly. In practice, this is the movement of ‘reaching out’ to something.
Retraction refers to the posteromedial movement of the scapula on the thoracic wall, which causes the shoulder region to move posteriorly i.e. picking something up.
What are muscles named on and based on
Muscle names are based on many factors 1 Location 2 Number of origins 3 Origin 4 Insertion 5 Shape 6 Size 7 Direction 8 Function
What is location

What are the 2 main hip flexors
The 2 main hip flexors are :
1 psoas (illopsoas) 2 rectus femoris (quadricep muscle that begins at the front of the hip joint)
What is the psoas
The psoas is a deep-seated core muscle connecting the lumbar vertebrae to the femur.
The psoas major is the biggest and strongest player in a group of muscles called the hip flexors:
What area of the hip does the mula and uddiyana lock
psoas muscle
When the psoas muscle is shortened what happens
1 pulls femur into the socket (limit mobility of hip) and tightens lateral rotators
2 causes abdominal muscles to tighten
3 causes compression of the lumbar spine
What is the Rectus Femoris
A muscle in the quadriceps,
the rectus femoris muscle is attached to the hip and helps to extend or raise the knee.
This muscle is also used to flex the thigh. The rectus femoris is the only muscle that can flex the hip.
What are the hip extensors
Gluteus maximus
The gluteus maximus (also known collectively with the gluteus medius and minimus, as the gluteal muscles (“glutes”) is the main extensor muscle of the hip.
What are the hamstrings
The hamstrings are a group of muscles and their tendons at the rear of the upper leg.
They include the
1 biceps femoris
2 semitendinosus
3 semimembranosus.
The hamstrings flex the knee joint, adduct the leg, and extend the thigh to the backside of the body.
They are used in walking and running.
What are the abductors of the hips
The hip abductor muscles include the
1 gluteus medius,
2 gluteus minimus,
4 tensor fasciae latae (TFL).
They not only move the leg away from the body, they also help rotate the leg at the hip joint.

c
Piriformis syndrome is a condition in which the piriformis muscle, located in the buttock region, spasms and causes buttock pain.
The piriformis muscle can also irritate the nearby sciatic nerve and cause pain, numbness and tingling along the back of the leg and into the foot (similar to sciatic pain).
