Parallel fiber

collagen fibers and depending on the direction these fibers are running the matrix can be categorized as dense regular or dense irregular. In dense regular collagenous connective tissue the collagen fibers run in the same parallel direction. Which helps tendons to attach muscle to the bone and ligaments to attach bones to other bones.…

modifying activity patterns of the upper motor neurons. The cerebellum receives its input from the spinal cord in form of mossy fibers that project from the pons and spinocerebellar pathways. Mossy fibers contribute the information necessary for the output from the motor cortex and sensory information about the state of the body. In addition, it also receives input from climbing fibers that project from the inferior olive, of which contribute information about the errors in movement. These…

higher nodes stays less time, they don’t complete all the development stages specially elongation. So higher the node, the length of the fibers becomes low. Fiber length is influenced largely by the extreme temperatures, water stress. The months that elongation occurs in higher nodes can experience these environmental conditions and form shorter fibers. 4) Cotton fiber development happen in four stages. They are differentiation, Initiation, elongation, secondary cell wall deposition and…

However, muscle fibers have vital physical features that develop two distinct types of fibers. The fast twitch, also known as type ii fibers, and slow-twitch fibers or type i fibers (Bidle, 2016). Muscles are also put in “compartments” a muscle compartment is known as, “a group of functionally related muscles enclosed and separated from others by…

1. The number of muscle fibers that are innervated by a motor neuron is dependent on what muscle it is. Fine motor movements, such as typing, would need only a few muscle fibers. This means that the thumb has only a few fibers, but the thigh, back, and biceps have many. These need a lot more force to be exerted, which is why they need more muscle fibers. Using your thumb and bladder does not require many muscle fibers. 2. Alpha motor neurons innervate extrafusal muscles but gamma motor neurons…

2.1. Biocellulose definition Cellulose is the main component of plant cell wall. Some bacteria produce cellulose (called biocellulose or bacterial cellulose). Plant cellulose and bacterial cellulose have the same chemical structure (Fig.2.1), but different chemical and physical properties (Lin et al., 2016). The molecular formula of bacterial cellulose (C6H10O5)n is the same as that of plant cellulose, but their chemical and physical features are different. Biocellulose is preferred over the…

Before we dive into the kinds of muscles and their functions, let’s get a better idea of how muscles work. According to medicinenet.com, “The contractile tissue made up of thousands of parallel, cylindrical fibers that run the length of the muscle (you could have 100,000 fibers in your biceps alone!). The fibers are made up of smaller protein filaments called…

Tendons are bands of fibrous connective tissue that connect muscles to bones(Pagorek et al. 2012). Their functions include mediating normal joint movement and stability and to contribute in maintaining body posture(Sharma & Maffulli 2005). Tendons injuries are frequent and cause joint dysfunction that can affect the performance in workplace. Work-related overuse disorders are most common in the tendons and tendon insertions of the upper extremities. The most commonly-affected tendons are in the…

A motor unit is a motor nerve and all the fibers that it innervates. Motor units make up muscles and they are recruited based on the size principle. This means that generally smaller motor units are recruited first. These motor units have less muscle fibers when compared to the larger motor units resulting in a lower force production. Motor units are recruited based on the amount of load as well. A…

(2008), turning cotton fibers to amazing blue, durable fabric takes three complex stages. The initial step in making denim is converting the cotton fibers to yarn. When farmers deliver the cotton fibers to the factory, workers who are receiving the cotton separate the fibers. The fibers are then fluffed and cleaned so they can be assembled and made to strands of yarn. After that, the workers align the fibers in parallel strands and remove the undesirable, short or defected fibers. Then, a…
