Examples of skeletal muscle include the biceps, triceps, calves, and pectoral muscles.
Skeletal muscles are voluntary muscles, meaning you consciously control their movement. They are attached to bones via tendons and are responsible for a wide range of bodily actions, from walking and running to lifting objects and even facial expressions. They contract and relax in response to signals from the nervous system, allowing us to move. Here's a closer look at the examples provided:
-
Biceps: Located on the front of the upper arm, the biceps muscle flexes the elbow and supinates the forearm (rotates the palm upwards).
-
Triceps: Situated on the back of the upper arm, the triceps muscle extends the elbow.
-
Calves: Found on the back of the lower leg, the calf muscles (primarily the gastrocnemius and soleus) plantarflex the foot (point the toes downwards) and are crucial for walking, running, and jumping.
-
Pectoral Muscles: Located in the chest, the pectoral muscles (pectoralis major and minor) adduct (bring towards the midline), flex, and rotate the arm.
In summary, skeletal muscles, like the biceps, triceps, calves, and pectorals, are essential for movement and are under conscious control.
