Skeletal muscle fibers
are cylindrical, multinucleated, striated, and under voluntary control.
Which type of muscle tissue is multinucleated quizlet?
skeletal muscle
: multinucleated!!!! skeletal muscle: voluntary, under conscious control.
What is multinucleated muscle tissue?
Skeletal muscle cells
, more commonly called muscle fibres, are multinucleated syncytia formed during development by fusion of mononucleated precursor cells, the myoblasts. … The electron micrograph shows part of the cytoplasm of a striated muscle fibre with parallel arrays of myofibrils.
Why is muscle multinucleated?
Skeletal muscle tissue is arranged in bundles surrounded by connective tissue. Under the light microscope, muscle cells appear striated with many nuclei squeezed along the membranes. … The cells are multinucleated as
a result of the fusion of the many myoblasts that fuse to form each long muscle fiber.
Is smooth tissue multinucleated?
Skeletal muscle cells are multinucleated from the fusion of muscle cells and smooth muscle cells
are strictly mononucleated
, and cardiac muscle cells are mononucleated in humans. … Smooth muscle is spindle shaped, and like any muscle, can contract and relax.
What do the three types of muscle tissue have in common?
- Terminal of motor axon interfaces with muscle cell. …
- Synaptic Cleft: Gap thru which transmitter diffuses.
What do the three muscle tissues 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 examples of muscle tissue?
- skeletal muscle (or the striated voluntary muscle) tissue.
- smooth muscle (or the non-striated involuntary muscle) tissue.
- cardiac muscle (or the heart muscle) tissue.
Where is muscle tissue found?
Smooth muscle fibers are located in
walls of hollow visceral organs
, except the heart, appear spindle-shaped, and are also under involuntary control. Skeletal muscle fibers occur in muscles which are attached to the skeleton.
How do you identify muscle tissue?
Muscle tissue can be categorized into skeletal muscle tissue, smooth muscle tissue, and cardiac muscle tissue. Skeletal muscle fibers are cylindrical, multinucleated, striated, and under voluntary control. Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations.
What cells in the human body are Multinucleated?
Liver cells
, muscle fibers, and osteoclasts are all normal cells that often have more than one nucleus. Cancerous cells and those infected with viruses can also have multiple nuclei at times. In addition to human cells, certain types of fungi have multinucleated cells. as well.
Do muscle cells divide?
Muscle: Muscle regeneration
When the muscle is damaged, these cells
are stimulated to divide
. After dividing, the cells fuse with existing muscle fibres, to regenerate and repair the damaged fibres. The skeletal muscle fibres themselves, cannot divide.
What is Class 9 muscle tissue?
Muscular tissue consists of elongated cells, also called muscle fibres. This tissue is
responsible for movement in our body
. Main function of muscular tissues is to provide movement to the body. Muscles contain special proteins called contractile proteins, which contract and relax to cause movement.
What is the most distinguishing characteristic of muscle tissue?
What is the most distinguishing characteristic of muscle tissue?
Its ability to transform chemical energy into mechanical energy
.
What is the main function of smooth muscle?
The primary function of smooth muscle is
contraction
. Smooth muscle consists of two types: single-unit and multi-unit. Single-unit smooth muscle consists of multiple cells connected through connexins that can become stimulated in a synchronous pattern from only one synaptic input.
What is unique about the muscle tissue the nervous tissue?
The key difference between muscular tissue and nervous tissue is that the
muscular tissue is a tissue specialized for contraction
, while the nervous tissue is a tissue specialized for communication.
