Histology 3 Joints, ligaments and skeletal muscle

Comments on lecture: pretty basic stuff on muscle anatomy basic contraction mechanism, and anatomy, mentions the triad which is new and goes a bit in depth on the Z line i one a zone and h zone

Objectives:

1. The architecture of the skeletal muscle and its connective tissue coverings
2. Features of a muscle cell/fibre
3. The mechanism of muscle contraction
4. The structural features of a sarcomere
5. Describe the structure and function of
   1. NMJ
   2. Muscle spindle
   3. Osteotendinous and myotendinous junction

Objective based questioning:

Content:

The architecture of the skeletal muscle and its connective tissue coverings

The order of contents is as follows:

2. Fascicles (covered by perimysium)
3. Muscle fibre/ cells (covered by endomysium)
4. myofibrils (covered by basal lamina and sacrolemma)
5. myofilaments (Actin and myosin)
