Human Physiology

In the structure of the myofibril, the thick filaments in a sarcomere are connected by a fibrous membrane. This membrane is known as the M-line. The M-line plays a crucial role in the structural integrity and the alignment of thick filaments (myosin) within the sarcomere.

Step 1: Understanding Homeostasis
- Homeostasis refers to the maintenance of stable internal conditions despite external changes.
- Homeothermy relates to warm-blooded animals maintaining a constant body temperature.
- Haemostasis is the process of blood clotting.
- Homozygous refers to having two identical alleles for a gene.
