What else can I help you with?
Are inorganic fibers natural or synthetic. name two?
Inorganic fibers are synthetic because they are not composed of organic matter, ie, wool, hemp, cotton.
What cell structures composed of microtuble fibers?
Microtubules are found in - cytoskeleton cilia flagella mitotic spindles
What is the structure of natural fiber?
Natural fibers are made up of long chains of molecules called polymers, which are composed mainly of cellulose, hemicellulose, and lignin. These polymers are organized into fibrils, which are further grouped into fibers. The arrangement of these fibers contributes to the strength and flexibility of natural fibers.
Portion of the brainstem composed of myelinated nerve fibers that connects to the cerebellum?
The portion of the brainstem composed of myelinated nerve fibers that connects to the cerebellum is the peduncles. The peduncles serve as pathways for communication between the cerebellum and other parts of the central nervous system, allowing for coordination of movement and balance.
Do the commissural fibers form the corpus striatum?
No, commissural fibers do not form the corpus striatum. The corpus striatum is primarily composed of the caudate nucleus and putamen, which are part of the basal ganglia. Commissural fibers connect the two hemispheres of the brain, such as the corpus callosum.
What are spindle fibers composed of?
Spindle fibers are composed of microtubules, which are polymers of the protein tubulin. These microtubules play a crucial role in cell division by helping to separate the chromosomes during mitosis and meiosis.
What is a bundle branch composed of?
Purkinje fibers.
What protein fibers are bone matrix composed of?
collagen
The anterior root of the spinal cord is composed of?
motor fibers
The protein fibers of the bone matrix are composed of?
The protein fibers of the bone matrix are mainly composed of collagen, which provides strength and flexibility to bones. These fibers are embedded in a mineralized matrix made of calcium and phosphate crystals, which contribute to the hardness and rigidity of bones.
The thick filaments of muscle fibers are composed of what?
Myosin
What are muscles?
Muscles are tissues composed of fibers, the contraction of which produces movement in the body.
Fibers of the cytoskeleton are composed of primarily?
Fibers of the cytoskeleton are primarily composed of three types: microfilaments (actin filaments), intermediate filaments, and microtubules. Microfilaments are primarily made of actin, intermediate filaments consist of various proteins like keratins and lamins, while microtubules are made of tubulin protein subunits.
Which fibers are seen in embedded in the matrix of connective tissue?
The matrix of connective tissue is composed of collagen, reticular, and elastic fibers embedded in ground substance (typically composed of water with stabilizing proteins). The fibers are made by fibroblasts and the most abundant in the body is collagen, while the least abundant is elastic.
Anterior root of the spinal cord is composed of?
The anterior root is composed of nerve fibers responsible for motor activity (i.e. efferent nerve fibers that will stimulate muscles, etc.). I think some of the things it is composed of include:Gamma motor neurons, alpha motor neurons, preganglionic autonomic neurons
Muscle sphincters are composed of what two types of muscle fibers?
Smooth Muscle Fiber
Are inorganic fibers natural or synthetic. name two?
Inorganic fibers are synthetic because they are not composed of organic matter, ie, wool, hemp, cotton.
