Bone Disorders01:29

Bone Disorders

5.7K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

4.4K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Overview of Skeletal Muscle

15.7K
Skeletal muscles are composed of a bundle of muscle fibers and are attached to bones through tendons. Each skeletal muscle fiber is a single muscle cell. The sarcolemma, the plasma membrane of a skeletal muscle cell, consists of a lipid bilayer and glycocalyx that supports muscle fibers. The sarcolemma extends into the muscle cells to form tubular structures called transverse or T-tubules. Each side of the T-tubules consists of a membrane-bound structure called the sarcoplasmic reticulum,...

Changes in the Appendicular Skeleton with Age

3.9K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Skeletal Muscle Anatomy

Skeletal muscle is the most abundant type of muscle in the body. Tendons are the connective tissue that attaches skeletal muscle to bones. Skeletal muscles pull on tendons, which in turn pull on bones to carry out voluntary movements.

Clearance Models: Physiological Models01:09

Clearance Models: Physiological Models

382
Drug clearance is a critical pharmacokinetic process involving the irreversible removal of drugs from the body through various organs over a specified time period. Physiological models are indispensable in determining organ-specific clearance, defined by the proportion of the drug eliminated per unit of time from the organ's blood volume.
The organ's clearance rate depends on the blood flow to the organ and the extraction ratio (E). The extraction ratio describes the organ's...

Area of Science:

  • Gerontology
  • Muscle Physiology
  • Aging Research

Background:

  • Sarcopenia affects 40-50% of individuals over 80, presenting a major geriatric clinical challenge.
  • Characterized by loss of muscle mass and strength without overall weight loss, sarcopenia leads to adverse clinical outcomes and increased mortality.
  • Physical frailty associated with sarcopenia contributes to balance disorders, falls, fractures, and pain, highlighting the need for therapeutic interventions.

Purpose of the Study:

  • To review existing animal models for studying sarcopenia.
  • To emphasize the importance of these models in advancing sarcopenia research and therapy development.

Main Methods:

  • Review of established animal models for sarcopenia research.
  • Models discussed include hind-limb unloading, denervation, immobilization (casts/wire), and aged rodent studies.

Main Results:

  • The review synthesizes information on various animal models used to investigate sarcopenia.
  • Highlights the utility of these models in mimicking aspects of age-related muscle decline.

Conclusions:

  • Currently, no registered treatments exist for sarcopenia.
  • Development and utilization of relevant animal models are essential for advancing research and developing effective therapies for sarcopenia.
  • Improved animal models are critical for understanding sarcopenia mechanisms and testing potential interventions to promote healthy aging.
