Myofibrils consist of contractile proteins called?
Myofilaments Two types: actin (thin filament) & myosin (thick filament)
Long filamentous organelle with a banded appearance?
A long filamentous organelle with a banded appearance is a myofibril. A myofibril is a cylindrical structure that extends along the complete length of each muscle cell.
The segment of a myofibril that is called a sarcomere runs from?
One Z line to the next Z line
What is the segment of a myofibril between two Z-lines?
sarcomereThe contractile units are called sarcomeres.
Muscle cells contain contractible units called?
Myofibril, composed of actin and myosin.
Which section goes into myofibrils organised along muscle fibers?
Myofibrils are composed of proteins such as actin, myosin, titin. These proteins are organized into thin filaments and thick filaments, which repeat along the length of the myofibril in sections called sarcomeres.
Does a myofibril have a banded appearance?
Yes, a myofibril has a banded appearance. The sarcomere is delimited by two dark bands which are called the Z-discs. The Z-discs have two lighter colored bands and two darker bands.
What is the order from largest to smallest myofibril fascicle myofiber myofilament?
myofilament myofibril myofiber fascicle muscle
What is the title for the information that precedes each section?
The title for the information that precedes each section is usually called a heading or subheading.
What another name for myocyte?
Myofibril
What is one of the functional units of a myofibril?
sarcomere
What is the term for a Smaller fiber in a muscle fiber?
The smaller fiber in a muscle fiber is called a myofibril. A band of tissue that connects bone to bone is called a ligament.
