Homework Answers
Answer no 2
a) A band- A Myofibril has dark & light bands, the dark bands are called A band or Anisotropic band.
b) I Band - Similarly in a myofibril, the light bands are called as I Band or Isotropic band.
c) Z disc- Each I band has a dark membrane at its centre called as Z line or Z disc . Z denotes word Zwischensciebe ( Zwischen = between & schiebe = disc).
d) H zone- At the centre of A Band , a comparatively less dark zone called as H zone./ Hensen zone.
e) M Line- In the centre of the H zone , there is M zone/ Mittleschiebe (mittle= middle).
In figure , Middle light line is M line,
Wide Light band is H zone
Dark line both the side showing a sarcomere.

SECTION 1: Structure of a Skeletal Muscle A. Layers of connective tissue separate a muscle into compartments. The layer called endomy- sium surrounds each muscle cell. Muscle cells are then bundled into fascicles, which are sur- rounded by perimysium. The entire muscle is composed of many fascicles, and is surround- ed by epimysium. All layers merge together to form the tendon that attaches the muscle to a bone. An outermost layer of connective tissue called fascia binds adjacent muscles together...

Compare and contrast the following traits for skeletal, smooth and cardiac muscle. You MUST clearly indicate which muscle tissue type you are referring to. Making a table is helpful. Number of nuclei in each cell Whether sarcomeres are present (yes or no sarcomeres?) Where the muscle type is generally found in the body (specify organ). For muscle tissues found in multiple places, name AT LEAST TWO places in the body (organs, not muscle names) where it can be found. Whether...

MUSCULAR SYSTEM Skeletal muscles allow our bodies to bend, walk, sit, chew and talk. Humans have more than 600 muscles in their bodies. Muscles are named in various ways: by the action they perform (extensor, flexor): by their size (maximus, minimus), or length (brevis, longus); by their shape (deltoid, trapezius); for their origin(s) or insertion(s) (sternocleidomastoid), or by the number of origins or insertions (triceps, biceps). In addition, they can be named for their location (abdominis, brachii) or the bones...
