Smooth muscles as the name suggests are smooth in appearance ie.

. When comparing skeletal cardiac and smooth muscle which of the following characteristics is unique to just one muscle type. Answer to Question 136641 in Biology for Galata. Smooth muscle fibers do not.

Only cardiac muscle is capable of autorhythmicity Only cardiac muscle has a high concentration of mitochondria. They are voluntary means they can be controlled. Smooth muscle depends on the calcium-calmodulin system to regulate contraction while skeletal muscle relies on the calcium-troponin system to regulate contraction.

Repolarization The refractory period in which the muscle will not contract if stimulated occurs during __________ of. Science Biology Anatomy Physiology Which of the following is unique to cardiac muscle cells. Heart muscles or cardiac muscles contain intercalated discs.

These muscle fibers are in turn composed of many chains of myofibrils. Four characteristics define cardiac muscle tissue cells. It resembles the skeletal type with reference to multinucleate cells and a striped appearance.

Sarcoplasmic reticulum is present in all three types of muscle tissue that is smooth muscle skeletal muscle and cardiac muscle tissue. It is present throughout arteries and veins where it plays a vital role in. They are called smooth or visceral muscles because they are found in the visceral organ of the body.

This muscle type is slow twitch and often rhythmic in contraction. Unlike skeletal muscle contraction in smooth muscle does not involve a sliding filament mechanism. The cross striation is absent in the smooth muscles so their fibres look smooth hence it is named non-striated.

Skeletal muscle fibers are located in muscles attached to the skeleton. Unlike skeletal muscle smooth muscle does not depend on ATP to fuel contractions. Which of the following characteristics can be used to describe epithelial.

D smooth 3 Which of the following is unique to cardiac muscle tissue. Correct option is A Spindle-shaped cells are present in smooth muscles. Sarcoplasmic reticulum is the specialized form of smooth endoplasmic reticulum SER which stores retrieves and releases calcium ions.

Skeletal muscle is described by all of the following EXCEPT. Only cardiac muscle has gap junctions. You can also find smooth muscle in the walls of passageways including arteries and veins of de cardiovascular systemThis type of involuntary non-striated muscle is also found in the tracts of the urinary.

- Skeletal muscle lacks the coarse connective tissue sheaths that are found in smooth muscle. They do not have striations on. Skeletal cardiac and smooth.

Step 1 of 3. Each fibre of the smooth muscle cells contains a thick oval nucleus in its thick middle part. It is in the stomach and intestines where it helps with digestion and nutrient collection.

There are three main types of muscles. A gap junction makes channels between adjacent muscle fibers or cells to connect their. A striated b voluntary.

Fibres of skeletal muscle tissue are long straight and unbranched. - Skeletal muscle fibers contain sarcomeres. Smooth muscle is present throughout the body where it serves a variety of functions.

Smooth muscle so-named because the cells do not have striations is present in the walls of hollow organs like the urinary bladder uterus stomach intestines and in the walls of passageways such as the arteries and veins of the circulatory system and the tracts of the respiratory urinary and reproductive systems abSmooth muscle is also present in the eyes. As far as similarity with smooth muscle is concerned both cardiac and smooth muscle types bear a nucleus in the center. Which of the following is a characteristic of a smooth muscle cell.

- Smooth muscle lacks the thin and thick filaments characteristic of skeletal muscle. It can be stimulated by hormones. A is involuntary b is non-striated c has intercalated discs d contains smooth muscle tissue.

Characteristics of Smooth Muscle. What substance is released from the axon terminal into the synaptic cleft at the neuromuscular junction. It relies on calcium which comes exclusively from the sarcoplasmic reticulum.

The smooth muscle cells consist of long narrow and unbranched spindle-shaped fibres. It is an. One of the characteristics worth mentioning is perfect coordination of the cells during contraction and beating of heart.

Smooth muscle Textus muscularis levis Smooth muscle is a type of tissue found in the walls of hollow organs such as the intestines uterus and stomach. They are non-striated and involuntary. Muscle cells are composed of muscle fibers or myocytes.

It exists throughout the urinary system where it functions to help rid the body of toxins and works in electrolyte balance. Which of the following characteristics is unique to smooth muscle. Unique to the cardiac muscle are a branching morphology and the presence of intercalated discs found between muscle fibers.

It is under the control of the somatic nervous system. Describe the characteristics the location as well as the function of each type of muscle tissue. 7 Discuss the main types of muscle tissue.

Only cardiac muscle contains a sarcoplasmic reticulum. - Skeletal muscle fibers tend to be shorter than smooth muscle fibers. Identify the location of both multiunit smooth muscle and single-unit smooth muscle and explain the A.

Is one of three types of vertebrate muscles with the other two being skeletal and smooth muscles. Smooth muscles are found primarily in the digestive tract esophagus small and large intestine urinary tract ureter bladder reproductive system uterus vaginal walls and endocrine system ducts. Smooth muscle is typically non-striated uni-nucleated and involuntary or reflexive.
