Human Anatomy: Muscles and Nervous System

Muscular Body and Facial Muscles

• Doctor Chris Gail explains the importance of muscular body and facial muscles.
• The facial nerve is responsible for controlling facial muscles and is connected to the brainstem.

Structure and Function of Muscles

• Muscles have a structural shape like a torch light sheet and ribbon of turn on life material.
• Muscles are connected to the nervous system and have a strategic position.
• There are different types of muscles, including the temporal branch and depression.

Clinical Importance of Muscles

• Muscles play a crucial role in facial expressions and emotions.
• Damage to muscles can lead to depression and anxiety.
• The front arm pits are an important area for muscle examination.
• A 40% tempo travel branch of the facial nerve is responsible for facial movements.

Examination and Diagnosis

• Muscles are examined through testing and differential diagnosis.
• The facial nerve is examined through a series of tests, including the 123-use test.
• Depression can be diagnosed through muscle examination and facial expressions.

Muscle Function and Movement

• Muscles are responsible for facial movements and expressions.
• The front arm pits are responsible for moving the head and looking forward.
• Normal horizontal wrinkle movement is an indicator of healthy muscle function.

Skin Structure

• The skin consists of three main structural layers: hypoderm (inner layer), derm (middle layer), and epiderm (outer layer).
• The stratum corneum (SC) is the outermost layer, consisting of corneocytes embedded in a lipid matrix.

Lipid Matrix Function

• The lipid matrix in the SC can be disordered, leading to increased permeability and compromised barrier function.
• The lipid matrix can also be affected by certain skin diseases, resulting in further disruption to its protective function.

Skin Diseases and Lipid Depletion

• Skin diseases such as psoriasis and atopic dermatitis are associated with decreased lipids in the SC.
• Decreased lipids in the SC can lead to skin dryness and irritation.

Lipid Synthesis and Skin Health

• The use of stearic acid as a carbon source for lipid synthesis can lead to increased production of ceramides (CER).
• Increased CER production can help reduce skin dryness and improve skin health.
