The document summarizes the muscular system, classifying muscles as voluntary or involuntary and describing the three main types - smooth, cardiac, and skeletal. It then discusses the muscles in different body regions, including the front and back limbs, trunk/head/neck, and provides a labeled diagram of cattle muscle groups. Key points covered are the functions of movement and life support, classifications of muscle types, and locations and actions of important muscles.
The muscular system is a complex network of tissues and organs responsible for movement, stability, and heat generation in the human body. Comprising more than 600 individual muscles, it enables various functions, including locomotion, posture maintenance, breathing, and circulation assistance. Muscles are composed of muscle fibers, which are elongated cells capable of contracting and relaxing to generate force. Skeletal muscles, attached to bones via tendons, facilitate voluntary movements, such as walking and lifting objects, under conscious control. Smooth muscles, found in organs like the digestive tract and blood vessels, perform involuntary functions like peristalsis and regulating blood flow. Cardiac muscle, exclusively present in the heart, sustains its rhythmic contractions to pump blood throughout the body. The muscular system works in coordination with the skeletal, nervous, and circulatory systems to ensure efficient movement and overall bodily function. Regular exercise and proper nutrition are essential for maintaining muscular health and strength throughout life.
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
It's fun to learn MUSCULAR SYSTEM...
This is primarily a synthesis of the topic including the different types of Muscular System, their movement, functions, sample practical exercises, categories on how muscles got its names, examples of diseases and its causes and effects, and a fun trivia to motivate the class...
Enjoy! God bless you all :)

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
2. Function of the muscular system
• Provides movement in conjunction with the
skeletal system
• Important in life support
• Used by humans for food
3. Classifications of Muscles
• Voluntary: Movement of the muscle is
under the control of the animal
• Involuntary: Movement of the muscle is
not controlled by the animal
4. Types of Muscles
• Smooth Muscles: Involuntary
muscles, found in the walls of
internal organs and the blood
vessels.
• Cardiac Muscles: Muscles that
form a network to make up the
heart.
• Skeletal Muscles: Have a
striped appearance, include
voluntary and involuntary,
attached to and moves your
bones. This is a majority of the
muscle tissue in your body.
5. Muscles of the Front Limb
• The largest and most
important muscle
attaching the front
legs to the body is the
serratus ventralis. It is
fan shaped and
supports the trunk of
the body between the
legs.
6. Muscles of the Back Limb
• The primary
movements are
extension and flexion.
• The main extensor
muscle of the hip is the
hamstring.
• Movement of the hock
is primarily
accomplished by
flexors and extensors
7. Muscles of the Trunk, Head
and Neck
• The loin muscle is
responsible for
extension of the spinal
column
• Many of the muscles
originate from the
vertebrae
• There is greater
flexibility in the neck
than in the spinal
column because of
the muscles within
Ask students why we need the muscular system before going over this slide.
Ask students if the following are voluntary or involuntary: Heart (cardiac), lungs (involuntary), bicep (voluntary), big toe muscles (voluntary)
Additional definitions: Flexor: decreases the angle between two bones when it contracts (biceps)
Extensors: Increases the angle between two bones when it contracts (triceps)
