Week 3 Flashcards
Ischium
Inferior lateral part of hipbone
Ilium
Wing of hipbone
Pubis
Medial anterior part of hipbone
Ischial tuberosity
Inferior part of ischium that is sat on
Ischial spine
Pointy part of ischium at posterior
Iliac fossa
Depression in ilium
Anterior superior iliac spine
Pointy bone part of ilium, on side of wing
Rami (superior and inferior)
Branches of pubis
Sub-pubic angle
Angle between pubis bones
Calcaneus
Heel bone
Talus
Tarsal that articulates with tibia
In sodium-potassium ion pump, each ATP molecule moves:
3 sodium ions out of the cell
2 potassium ions into the cell
Sarcolemma
Outer membrane of muscle fibre
Transverse tubules
Tube-like extensions of the sarcolemma.
Conduct electrical signals to the core of the cell.
Action potentials
Electrical signals
Sacroplasmic reticulum
Membrane network in muscle fibres.
Stores calcium.
Excitation-Contraction Coupling
The pairing of a signalling event and a mechanical event
Voltage-gated sensor (DHPR)
Received signals from transverse tubules and interacts with ryanodine receptors
Ryanodine receptors (RyR)
Passive calcium channel on the sarcoplasmic reticulum
SE calcium-ATPase (SERCA)
Active calcium pump, moves calcium back into sarcoplasmic reticulum to end excitation
