Laboratory Activity 5:
Muscular System
1
, Introduction
The most abundant and one of the most adaptable tissues in the body is the muscle tissue.
There are three types of muscle tissue: skeletal, cardiac, and smooth. Seen as a whole, the
muscular system is responsible for the movement of the body. It does not only control and
maintain movement while the body performs locomotive gestures or actions, but the
muscular system is also at work internally in the forms of muscle contractions within the body
(VanPutte et al., 2016, 150).
Aside from movement, the muscular system serves other major functions such as
maintenance of posture where the skeletal muscles maintain tone. Another is respiration
where the muscles of the thorax perform necessary contractions and movements during
respiration. Muscles are also involved in movements and actions needed for communication
like speaking, writing, facial expressions, and more. Moreover, when muscles contract, the
following occur: (1) heat is produced as well which contributes to the maintenance of body
temperature; (2) constrictions of organs and vessels which contributes in the functioning of
such organs; and, (3) and contractions of the heart muscles regulates the continuous blood
circulation (VanPutte et al., 2016, 150-151).
The laboratory activity, Muscular System, consists of activities and tasks that allows the
participants to: (1) illustrate and identify the muscular system; (2) distinguish the effects of
muscle fatigue on muscle function; and, (3) understand the effect of temperature on muscle
function. The activities aim to achieve the aforementioned objectives through various
procedures and processes in order to supply better understanding and knowledge of the
muscular system.
