What is the only human tissue capable of shortening or contracting?
What is the only human tissue capable of shortening or contracting?
The only human tissue capable of shortening, or contracting. A single motor neuron and all of the muscle cells that it stimulates. a disorder characterized by progressively worsening muscle weakness and loss of muscle tissue. skeletal muscle is also known as striated muscle and voluntary muscle.
Which type of muscle tissue specializes in contraction or shortening?
The type of muscle tissue that specializes in contraction or shortening is cardiac smooth and striated.
Which human body tissue has the ability to lengthen and shorten?
muscle tissue
A unique property common to all three types of muscle is contractility, which is the ability of the cells to shorten and generate force. While muscle tissue can shorten with contractions, it also displays extensibility or the ability to stretch and extend beyond the resting length of the cells.
Which type of muscle tissue allows voluntary movement?
Skeletal muscle, attached to bones, is responsible for skeletal movements. The peripheral portion of the central nervous system (CNS) controls the skeletal muscles. Thus, these muscles are under conscious, or voluntary, control.
What muscle moves when you want to move?
Skeletal Muscles
Skeletal Muscles – These are the muscles we use to move around. They cover our skeleton and move our bones. Sometimes they are called striped muscles because they come in long dark and light bands of fibers and look striped. These muscles are voluntary because we control them directly with signals from our brains.
Which type of muscle tissue is the only one that can respond to voluntary nervous stimulation in most people?
Which type of muscle requires voluntary nervous stimulation for activation? In order to contract, skeletal muscle fibers must be voluntarily stimulated by the nervous system. The site of muscle stimulation, where the nerve fiber communicates with the muscle fiber, is called the neuromuscular junction.
What type of muscle has branching cells?
Cardiac muscle
Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks.
What produces striations in muscle tissue?
The striations are caused by the regular arrangement of contractile proteins (actin and myosin). Actin is a globular contractile protein that interacts with myosin for muscle contraction. Skeletal muscle also has multiple nuclei present in a single cell.
What do the three muscle tissue have in common?
All three muscle tissues have some properties in common; they all exhibit a quality called excitability as their plasma membranes can change their electrical states (from polarized to depolarized) and send an electrical wave called an action potential along the entire length of the membrane.
What are the 4 major functional characteristics of muscle tissue?
All muscle tissues have 4 characteristics in common:
- excitability.
- contractility.
- extensibility – they can be stretched.
- elasticity – they return to normal length after stretching.
What are the three types of muscle tissue voluntary?
The three types of muscle cells are skeletal, cardiac, and smooth. Their morphologies match their specific functions in the body. Skeletal muscle is voluntary and responds to conscious stimuli.
