Hint: Smooth muscles are involuntary muscles that are found in humans, they carry out the process of excitation on their own and are not under the influence of any voluntary force. Based on their presence in a group or clusters they are divided as Single-unit and Multi-unit smooth muscles.
Complete answer: The difference between single-unit smooth muscle and multi-unit smooth muscle is as follows-
Additional information: 1. There are 5 main properties of the muscular system are :
Excitable or Irritable, Contractible, Extensible, Elasticity, Adaptability.
2. The important functions of the muscular system are as follows:
Mobility -The muscular system's main function is to allow movement,
Stability - Muscle tendons stretch over joints and contribute to joint stability,
Posture, Circulation, Respiration, Digestion, Urination, Childbirth.
Note: It should be noted that the name single unit is given as they function as one single unit while the others are termed as multiunit because they function as individual units.
Complete answer: The difference between single-unit smooth muscle and multi-unit smooth muscle is as follows-
SINGLE UNIT SMOOTH MUSCLE | MULTIUNIT SMOOTH MUSCLE |
These are connected using gap junctions | Gap junctions are not seen |
They act as a single functional unit | They act as multiple individual units |
Syncytium is present | Syncytium is absent |
They show the activity of the pacemaker | The activity of the pacemaker is not observed |
Affected by muscle stretch | No affect by muscle stretch |
contraction is not localized, rather found as a single unit. | 6. contraction is discrete and localized |
The autonomic nervous system is said to modify the response caused by these muscles | 7. The autonomic nervous system can not modify the response caused by these muscles. |
These are found in Gut, uterus, and bladder | 8. These are found in eye muscles, in and large blood vessels |
