How are cardiac muscle, smooth muscle, skeletal muscle alike?
AysviL [449]

Answer:

They are alike because they perform Voluntary and Involuntary Controls.

Explanation:

1). Skeletal muscle: The skeletal muscle brings about movement by pulling on the skeletal parts of which they are attached. This is the type of movement that is responsible for locomotion.

2). Smooth Muscle: This muscle is composed of elongated spindle-shaped cells which are grouped into bundles or sheets. They are least specialized muscle cells and are under the control of the autonomic nervous system.

3). Cardiac muscle: This muscle is only found in the walls of the heart. The muscle cells are branched and connected to one another by special discs. These cells helps the cells to contract and relax in unison so that the heart can pump rhythmically.

In the limbs, the flexion decreases the angle in the bones while extension increases the angle between the bones.  

The abduction- adduction motions involve the medial-lateral motions of the bones in which Abduction moves the limb away from the midline of the body while adduction moves limb toward the midline.

Circumduction is the movement of a body region in a circular manner while rotation is the movement of the body part around its own axis.

Inversion and eversion are the complex movements in which inversion is the turning of the foot toward the midline or inward movement while eversion is reverse of this.

Thus, the selected options are the correct answer.
