Insights from Neuroanatomy class.
The Accessory XI nerve, a cranial nerve, is vital for controlling the trapezius muscle, which facilitates various neck and shoulder movements. When stress occurs, this muscle can tense up, leading to neck discomfort. Interestingly, in quadrupeds like cats, the trapezius muscle is crucial for lifting the head; this adaptation aids grazing animals in responding to external stimuli. Additionally, the short-term memory (STM) muscles also contribute to raising the head, illustrating the complexity of our muscular system's evolution and functionality.

#1 University of California – Berkeley
Located in the Bay Area, the University of California, Berkeley is the best U.S. public college, according to Forbes’ 2023 analysis.The public research university offers more than 300 degree programs, including sustainable environmental design, aerospace engineering and Chicanx Latinx Studies.
Founded in 1868, the university’s establishment stems from a vision in the state’s constitution to “contribute even more than California’s gold to the glory and happiness of advancing generations.”

Ring of Fire
In the cosmos where shadows meet the light,
A ring of fire, both day and night,
Symbolic of our human tale,
Where peace and war together sail.
In annular eclipse, the moon tries to hide,
Yet leaves a ring on the sun's bright side,
A metaphor, profound and vast,
Of struggles in our world so vast.
Amidst the fire, shadows play,
A reminder of both night and day,
In conflicts' ring, let's seek the grace,
To find the light in darkest space.

Oct 14 was an Annular Eclipse where the three celestial bodies the Earth, Moon and Sun line but except the Moon is at apogee which is the furtherest away from the earth, so it does fully cover the sun, leaving a ring of fire effect.
The ring of fire can be seen as a metaphor for the delicate balance between opposing forces - like peace and conflict - in the world. It reminds us that even in moments of darkness of the complexities of human discord (the shadow), there is always a glimmer of hope and light (the ring of fire) - it is the potential for positive change even in challenging times.
Mickey Mouse on our Mind
Mickey Mouse on our Mind.
When we think of the brain, we often imagine a complex network of neurons and synapses, working tirelessly to govern our thoughts, emotions, and actions. But did you know that there's a part of our brain that resembles the iconic Mickey Mouse; science meets imagination. Who knows, perhaps Walt Disney drew inspiration for his Mickey character from from brain imaging.
Ears are the Cerebrellar Peduncles, Eyes are the Red Nuclei, Eyebrows are the Substantia Nigra, mouth is the cerebra aqueduct and around the mouth is the PAG.
The Complex Terrain of Muscle Contraction - Insights from Disability
(Based on topic covered in Neuroanatomy Class along with some additional disability perspectives. )
In the world of biology, muscle contraction is a fundamental process, enabling us to move and function. The way our muscles contract, however, can lead to various consequences, especially when disrupted by factors like bacterial infections.
Muscle contractions are driven by motor units. Whether the contraction is strong or weak depends on how many of these units are activated. So a fine precise motor action requires small number of units activated and need little strength.
Tetanus, caused by bacteria, takes this natural muscle contraction process to an extreme, forcing every single motor fiber in a muscle to contract simultaneously, causing intense pain that is hard to put into words.
Understanding muscle pain takes us to the basics of cellular respiration. Muscles, like all cells, need oxygen, which is supplied through arteries. When a muscle contracts and restricts this oxygen supply, it creates a problem. The muscle cells continue to function, breaking down glucose in the absence of oxygen. However, this process produces lactate, leading to a burning sensation, indicating the body's distress.
This pain can have severe consequences. In intense muscle contractions, essential muscles like the diaphragm, responsible for breathing, can weaken. Chest muscles may become so tense that they hinder the natural process of inhaling and exhaling.
In the complexity of our body's workings, this delicate balance between muscle contraction and relaxation defines our abilities. Understanding these intricacies not only enhances our knowledge of our biological marvel but also emphasizes the need to appreciate and preserve the balance that allows us to move and function seamlessly.
There exists a parallel narrative, one that often goes unnoticed — the experience of autistics. Consider a autistic whose sensory perceptions are heightened and processed differently. The involuntary muscle contractions experienced by autistics might not only induce physical discomfort but also trigger heightened sensory responses, amplifying the distress. In such cases, the pain isn't merely a physiological phenomenon; it extends into the realms of sensory overload, creating an overwhelming and sometimes unbearable experience.

Understanding muscle contraction through the lens of disability offers profound insights into the human experience. It urges us to delve deeper, to acknowledge the diverse ways in which individuals perceive and process pain. In doing so, we foster empathy and compassion, paving the way for inclusive healthcare practices that cater to the unique needs of every individual, irrespective of their physical or neurological differences.
Dispel notion that any medical intervention is inherently harmful
To drive true progress and improve the quality of life of all autistics we need BOTH Strengths_based_Opportunities AND Challenges_based_Solutions.
It is not Either-Or.

Contemplation
Altruism transforms selflessness into a profound connection, weaving the fabric of humanity with threads of compassion and understanding. - Hari Srinivasan
Contemplation, one line a day
Hope is the promise of a better tomorrow, a brighter future, and a more compassionate world.- Hari Srinivasan
