Muscles

Muscles are contractile tissues that enable movement in animals. They are composed of elongated cells containing protein filaments (actin and myosin) that slide past each other, causing contraction and force generation. muscles play a critical role in locomotion, maintaining posture, stabilizing joints, and generating heat. Different types of muscles include skeletal muscles (voluntary), smooth muscles (involuntary), and cardiac muscles (involuntary and specific to the heart). They are involved in a multitude of functions, from fine motor skills to powerful contractions, vital for survival and daily activities. These tissues work together in a coordinated manner to achieve the body's required motion and stability.
