attach at the top of the ischium at base of pelvis, pass back of knee & attach to top of tibia
Length is vital for dancers to enable movements such as kicks and splits safely

38
Q

A

Outside of back of leg
Extends thigh and flexes knee
Rotates leg outward

39
Q

rotates leg inward

40
Q

Semimembranosus

A

Deeper muscle to Semitendinosus
extends thigh and flexes knee
Rotates leg inwards

41
Q

Muscles of lower leg

A
Calf region contains muscles responsible for movement of foot
Gastrocnemius
Tibialis Anterior
Extensor Digitorum Longus
Peroneus Longus
Soleus
42
Q

Gastrocnemius

A

Large muscle at back of lower leg (calf) forms the main curve
attached from the heel by achilles tendon
plantar flexes foot (points)
can flex knee when foot is dorsiflexed

43
Q

Tibialis Anterior

A

Muscle extends down along the outer edge of the tibia from knee to foot
allows dorsiflexion and inversion movement of foot

44
Q

Extensor Digitorum Longus

A

Muscle extending from knee down to toes
slightly deeper and more lateral to tibialis anterior
extends toes and helps dorsiflexion of foot

45
Q

Peroneus Longus

A

Muscle extending from below knee to ankle on outside of lower leg
Plantar flexes foot and raises side of foot outward (eversion)

46
Q

Soleus

A

Broad, flat muscles that extends from below knee to heel
Deep to the gastrocnemius
Plantar flexes foot
Very important for locomotor and postural control

47
Q

A
Achilles tendon
Patella ligament
Iliofermal and Pubofemoral ligaments
Tibial collateral ligament 
Fibular collateral ligament
48
Q

Achilles’ tendon

A

Strongest tendon in the body

Connects the lower portion of Soleus and the gastrocnemius to the back of the calcaneus

49
Q

Patella ligament

A

Continuation of the central portion of the tendon of the quadriceps femoris group over the kneecap and down to the upper end of the tibia

50
Q

Iliofemoral and pubofemoral ligaments

A

Y-shaped ligament

Two ligaments help control the degree of movement possible in the hip

51
Q

Tibial collateral ligament

A

Inside of the knee joint connecting the femur to the tibia

Overstretching weakens the integrity of the knee joint and must be avoided

52
Q

Fibular collateral ligament

A

Outside of knee joint connecting the femur to the tibia

Overstretching weakens the integrity of the knee joint and must be avoided

53
Q

What is the musical tree

A

Semibreve- whole note equal to four crotchet beats
Minim- half note equal to 2 crotchet beats
Crotchet- quarter note equal to one count of the music
Quaver- eight note equal to half a crotchet beat
Semi quaver- sixteenth note equal to half a quaver beat

54
Q

Rhythm

A

The organisation of beats within a bar according to strong and weak beats

55
Q

Tempo

A

Indicated at the top of a sheet of music
Indicated by a metronome mark indicates number of beats per minute
How fast or slow a piece of music is played

56
Q

Accent

A

Symbolised by an arrowhead above or below a note
Indicated the note is to be played with force
Gives light and shade to a piece of music

57
Q

Syncopation

A

Particular type of rhythm where the and count is accented rather than the beat

58

59
Q

Origin and definition

A

The origins of classical ballet come from the early 16th, 17th and 18th century social and court dances. It was in the 19th century when classical teachnique as we know it today was created.

Most movements start and finish in one of the five positions of the feet or in a position derived from one of them. The arms and head are positioned and move according to certain rules. The basis of these rules lies partly in the natural laws of balance and opposition and partly in the aesthetics of a formal harmony of line.
