Which type of muscle tissue has intercalated discs?
Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks.
What type of muscle tissue is concerned with locomotion?
Skeletal muscle is attached to bones and its contraction makes possible locomotion, facial expressions, posture, and other voluntary movements of the body.
Which type of muscle tissue has intercalated discs quizlet?
What muscle cell type has intercalated disks? cardiac muscle has intercalated disks.
Which type of muscle tissue is composed of fibers with intercalated discs?
Cardiac muscle fibers cells also are extensively branched and are connected to one another at their ends by intercalated discs. An intercalated disc allows the cardiac muscle cells to contract in a wave-like pattern so that the heart can work as a pump.
What is an intercalated disc?
Intercalated disks represent the undulating double membranes where two cells are tightly bound together by desmosomes and connected by gap junctions, allowing electrical impulse conduction from cell to cell.
Are intercalated discs and striations found in skeletal muscle?
Explanation: Cardiac muscle and skeletal muscle both have striations due to their structure, but intercalated discs are only found in the cardiac muscle.
Where are skeletal muscle location?
Where are the skeletal muscles located? There are skeletal muscles throughout your body. They’re located between bones.
What type of muscle is striated with intercalated discs quizlet?
Cardiac muscle: Description: branching, striated, generally uninucleate cells that interdigitate at specialized junctions (intercalated discs).
Is transitional epithelium stretched and unstretched?
Transitional epithelium is a stratified tissue in which the cells are all have a fairly round shape when the organ it lines is not distended (stretched out).
What muscle tissue contains Myofilaments?
striated skeletal muscle
Types of muscle tissue are striated skeletal muscle and cardiac muscle, obliquely striated muscle (found in some invertebrates), and non-striated smooth muscle. Various arrangements of myofilaments create different muscles. Striated muscle has transverse bands of filaments.
Why dont skeletal muscles have intercalated discs?
Skeletal muscle – These fibers are unbranched and lack the intercalated discs found in cardiac muscle and are therefore not electrically connected. This feature allows them to contract independently (something that will be important in the next lab you do in ZO 250).
Which muscle has fibers joined by intercalated discs?
Cardiac muscle is striated muscle that is present only in the heart. Cardiac muscle fibers have a single nucleus, are branched, and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and desmosomes to hold the fibers together when the heart contracts.
Does smooth muscle contains intercalated discs?
Cardiac and skeletal muscles are “striated” in that they contain sarcomeres and are packed into highly regular arrangements of bundles; smooth muscle has neither. While skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles (called intercalated discs).
What type of muscle tissue has several nuclei per cell?
Answer: Smooth muscle cells usually have one nucleus per cell and the nucleus resides in the center of the cell. Striated muscle cells contain multiple nuclei located at the periphery.
What type of muscle tissue has multinucleated in it?
Skeletal muscle fibers are multinucleated structures that compose the skeletal muscle. Cardiac muscle, found within the heart, have fibers with one to two nuclei and are physically and electrically connected to each other so that the entire heart contracts as one unit.
