Study Notes
Muscle Anatomy and Function
- The word root "dyn" refers to strength.
- The word root "my" refers to muscle.
- The term "origin" refers to the attachment of a muscle to a non-moving bone or structure.
- The term "adduction" describes moving a body part toward the midline.
- The term "circumduction" means to make a circle with part of the body.
- The term "anteversion" describes bringing a part of the body forward.
Muscle Actions
- The term "elevation" describes raising the shoulders or closing the jaw.
- The term "flexion" describes bending a body part anteriorly (except in regard to the knee).
- The term "rotation" means to spin on an axis.
- A fixator is a muscle that stabilizes a joint, allowing other muscles to move.
Muscle Structure and Function
- The rectus abdominis muscle functions to compress the abdominal contents.
- The frontalis muscle originates from the epicranial aponeurosis.
- The sartorius muscle functions to flex the knee and rotate the femur laterally.
- The gastrocnemius and soleus muscles work together to plantarflex the foot.
Nervous System
- The two major divisions of the nervous system are the central nervous system (CNS) and peripheral nervous system (PNS).
- The CNS consists of the brain and spinal cord.
- The PNS consists of nerves that connect the CNS to the rest of the body.
- The cerebrospinal fluid (CSF) functions to cushion and protect the brain and spinal cord.
- The meninges are the membranes that cover the brain and spinal cord.
- The cerebral cortex is divided into lobes, including the frontal lobe, which is responsible for motor function and general senses like touch.
Muscle Contraction
- The theory of muscle contraction involves thick myofilaments grabbing thin myofilaments and pulling them toward the center of the sarcomere.
- A power stroke is the movement of the thick myofilaments toward the center of the sarcomere.
- In the relaxation phase, calcium is actively transported back to the sarcoplasmic reticulum.
Nutrition and Muscle Function
- The recommended daily allowance of protein for a person of average weight is 0.8 grams per kilogram of body weight.
- The mineral magnesium is required for muscle cell function, in addition to essential and non-essential amino acids.
Other
- The muscular system functions to maintain posture, regulate body temperature, and facilitate movement.
- The term "intrinsic" refers to muscles that originate within a body part, whereas "extrinsic" refers to muscles that originate outside of a body part.
- The term "hernia" refers to a condition where part of the viscera protrudes through the abdominal wall.
