Parallel fiber

known for its sufficient mechanical properties, and great flexibility. It also has great fracture toughness. Bamboo is considered to be a bio composite, meaning it encompasses multiple biological features and traits. It has a honeycomb structure of fibers, along with the cellular configuration of a parenchyma ground. Within the bamboo culm, there are hollow vessels that help pass nutrients throughout the plant. Bamboo…

Ligaments connect bones together and are made up of grossly parallel, fibrous, dense connective tissue.1 Many ligaments are parts of anatomically inseparable structures known as joint capsules, and this is certainly the case with the wrist. Ligaments often have a more vascular overlying layer termed the "epiligament" covering their surface. This layer is often indistinguishable from the actual ligament and merges into the periosteum of the bone around the attachment sites of the ligament.7…

Created in 1965 by Stephanie Kwolek, Kevlar is a synthetic fiber that can be used in a wide variety of ways [1]. It is used to make body armor, tires and automotive belts. Governments around the world use this material to protect their soldiers in combat, motorcyclists use it to protect themselves against road rash in the event of a crash, and it is also utilized in ropes and cables. While these uses for Kevlar have revolutionized personal protection, there is one particular application for…

As I closely observed the cadaver, this muscle has two heads; the superficial head arising from the medial epicondyle of the humerus and the deep head arising from the ulna head. These two heads has parallel muscle fibers inserting directly onto the middle of the radius. It is innervated by the median nerve arising from the medial epiconedyle that passes between the two heads pronator teres. This nerve gets pinched between the two heads causing pronator teres…

maximal contractions occurring in short bouts. It also focuses on muscle hypertrophy, or the enlargement of muscle fibers (Knuiman, 2015). Due to this fact, skeletal muscle adapts to each type of exercise very differently. To understand how skeletal muscle fibers…

In 1870, Camille Poirier started a shoe and leather goods store in Duluth, Minnesota. His first pack, the #3 Duluth Pack, that was available only in olive drab, was patented by Poirer in 1882. He expanded the products offered, to include wagon covers, auto packs, and shell bags for hunters. In 1911, he moved his shop to a larger building. During the Great Depression, more repairs were performed than new packs produced, but in the 1940's when the economy prospered and recreation soared,…

Behavioral and Neural Events in the Olfactory System Olfaction is dependent on a large network of multiple primary and secondary processing centers connected in parallel and serial manners. Some of these centers are linked with non-olfactory regions. Olfactory receptor neurons project into the olfactory bulb which projects to the olfactory cortex. The olfactory cortex is a three layered cortex with several distinct sub-regions, the largest being the pyriform cortex. The other main components of…

Lens Fiber Differentiation and its effects on certain organelles. This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used…

energy production occur with age; anaerobic enzymes seem to remain constant with age, while aerobic energy production is decreased with age. Age-related changes in muscle fiber distribution have been identified. While there is no consensus as to the exact numbers, it is clear that aging leads to an increasing percentage of type I fibers compared to type II. Similarly, general muscle strength decreases with age, possibly related to decreased contribution from the progressively smaller numbers of…
