Yes they do lack striations. They do not have striations because they do not have sarcomeres. Instead, smoothe muscle contracts as one unit through the use of electrical impulses.

Are smooth muscles striated or smooth?
Smooth muscle is the muscle inside of the digestive system so it has to be involuntary.
Skeletal muscle fibers differ from typical cells in that these muscle fibers?
Skeletal muscle fibers differ from typical cells in that these muscle fibers have many nuclei. The skeletal muscle store calcium ions in the sarcoplasmic reticulum.
When a sportsman runs he get muscle cramps why?
as there is a lack of oxygen in his muscle cells anothe pathway for brewakdown is akenits converted to lactic acid which accumilates in our muscles maria :)
What causes us to breath faster?
Lack of oxygen in the cells. Cellular respiration requires oxygen. Without oxygen, the cells acquire the energy they need from lactic acid fermentation. (This is the cause of muscle pain after workouts).
What is muscle atrophy?
Muscle atrophy refers to the wasting or loss of muscle tissue resulting from disease or lack of use.
What muscle that lack striations?
smooth
Do smooth muscle cells posses central nuclei but lack striations?
Smooth muscle is not striated, hence the name smooth muscle.nonotcardiac muscle
How do voluntary and involuntary muscles compare?
Voluntary muscles are generally skeletal muscle, controlled by the somatic nervous system. These have the long, striped cylindrical tubular cells most people think of when they think of muscle tissue. Involuntary muscles are generally smooth muscles that are spindle-shaped, lack striations, and are controlled by the autonomic nervous system.
Parts and functions of smooth muscle?
Smooth muscle cells contain filaments called actin and myosin that extend the lengths of the cells, but these filaments are organized differently than striated muscle. Smooth muscle cells lack striations and appear "smooth" under the microscope. There are two types of smooth muscle. They are multiunit and visceral. The multiunit are not found in sheets. This found in the irises of the eye and in blood vessels. They respond to nerve stimulation and some hormones. Visceral smooth muscles are found in sheets and they are found in hollow organs. They stimulate each other forming waves. These don't tire easily and do not lose pressure when distended.

Why are smooth muscles called smooth?
Smooth muscle is no way connected to the skeleton, example intestine liver etc. Where as striated muscle is connected to skeleton so it is called striated muscle. And the third type of muscle is Cardiac Muscle. --------------------------- Smooth muscle lack the sarcomeres that give skeletal and cardiac muscles their 'striated' appearance. Skeletal muscle isn't "called striated" because it it attached to the skeleton, it is called striated because sarcomeres give muscle a striated appearance. Thus the name, smooth muscle for looking smooth without striation.
Do skeletal muscles lack the coarse connective tissue sheaths that are found in smooth muscle?
False
What is the cause and effect of muscle cells lack adequate oxygen?
Me too quero saber

Which equation represents a process that results from lack of oxygen in human muscle cells?
glucose ---------> lactic acid + ATP
