muscular system is one of the most complex organ systems in the body‚ and it is imperative to the body’s survival‚ as it serves many significant functions‚ including movement‚ protection‚ posture‚ and heat production just to name a few. The muscular system has three types of muscle: skeletal‚ smooth‚ and cardiac. However‚ the main focus will be on the skeletal muscles and how they contract‚ as well as fatigue and respond to changes in temperature. In terms of the anatomy of the skeletal muscle‚ it

Skeletal Muscle Lab Introduction: Motor neurons and muscle fibers are the building blocks of motor units and where they intersect is called the neuromuscular junciton. The region where the flattened end of a motor neuron transmits neural impulses to a muscle is the motor end-plate. The end plate potentials depolarizes skeletal muscle fibers caused by neurotransmitters binding to the postsynaptic membrane in the neuromuscular junction. The process of contraction of the muscle cell is called excitation-contraction
Premium Neuromuscular junction Skeletal muscle Muscle
Skeletal muscle is a voluntary and striated muscle that attaches to the skeleton to allow control over posture and movement. Each skeletal muscle consists of bundles of muscles fibers called fascicles. These fascicles are composed of many individual muscle fibers or muscle cells that can be up to several millimeters long. These muscle fibers are composed of myofibrils‚ which are organized into thick filaments‚ myosin‚ and thin filaments‚ actin. These filaments are organized into repeating structures

2. FLNB in Skeletal Diseases Mutations in FLNB lead to various skeletal malformations‚ involving long bone‚ joints and vertebra. There were five FLNB-related skeletal disorders been reported so far‚ including spondylocarpotarsal synostosis (SCT)‚ Larsen syndrome‚ atelosteogenesis (AO)‚ boomerang dysplasia‚ and isolated congenital talipes equinovarus. (1) Spondylocarpotarsal synostosis syndrome (SCT‚ OMIM 272460) Spondylocarpotarsal synostosis syndrome was characterized by the following features:

The key bones involved in a rugby tackle vary throughout the whole body. The specific bones used are part of the appendicular skeleton that consist of bones that control the limbs of the body. This boners are specifically located in the uppper-chest/arm area and the leg area. For the upper-chest/arm area‚ the predominant bones involved include‚ the scapula‚ humerus‚ clavicle‚ radius and ulna. As for the leg area‚ the prevalent bones invloved in a rugby tackle include the hip flexor‚ femur and tibia
