The fovea centralis is tightly packed with receptors which can receive clear and highly detailed information.
The fovea centralis, or fovea, is a small depression within the neurosensory retina where visual acuity is the highest.
The fovea itself is the central portion of the macula, which is responsible for central vision.
To form high resolution images, the light must fall on the fovea, and that limits the acute vision angle to about 15 degrees.
In low light, this fovea constitutes a second blind spot since it is exclusively cones which have low light sensitivity.
Human fovea consists of 3 spectral types of cones: long wavelength cones, medium wavelength cones and short wavelength cones.

When sarcomeres shorten, the muscle fiber SHORTENS.
Mechanism :
Sacromeres are used to construct the myofibrils, which are a part of the skeletal muscles of animals. They use the sliding filament model to carry out the muscle contraction and relaxation.
To create movement, The cross-bridge between actin and the myosin heads causes the sacromere to shorten. Muscle fibers contract as a result of this shortening of the sacromere, which has the overall effect of shortening the fibers.
