Trapezius
Divisions
Upper
Middle
Lower
Because their attachments and actions are different
Trapezius - three different parts
Upper fibers
A, O, I
A -
bilaterally: extend the head and neck
Unilaterally: elevate the scapula (scapulothoracic joint) & upwardly rotate the scapula (s/t) joint
O - superior nuchal line, EOP (external occipital protuberance) and nuchal ligament (axial)
I - lateral 1/3 clavicle (anterior surface/appendicular)
Named for its shape
Trapezius
Named for
Shape - trapezoid
Bony attachments to know
- EOP or external occipital protuberance
- superior nuchal line of the occiput
- spinous process
- lat 1/3 of clavicle
- spine of the scapula
- ligamentum nuchae: ligament that extends posteriorly and runs from EOP to the S.P. of the C7
Bones of spine and thorax
Cervical vertebrae - 7
Thoracic vertebrae - 12
Lumbar vertebrae - 5
Breakfast at 7, lunch at 12 and dinner at 5

Nervous system
Functions
Sensations
Integration
Motor response
Nervous system
Structures
Brain
Spinal chord
Nerves
Sensory receptors
Nervous system
Sensations
sensory recptors detect stimuli within and outside the body
Nervous system
integration
integrates sensory information by analyzing and storing some of it and by making decisions for appropriate responses.
Nervous system
Motor Response
Once sensory stimuli is received, the nervous system may elicit an appropriate motor response
Types of glands
Exocrine
Endocrine glands
Endocrine glands
Ductless
Secrete directly into the bloodstream
Endocrine system
Structure
Glands that secrete hormones into the blood
Endocrine system
Functions
Regulate body activities and balance/homeostasis via negative feedback loops
Feedback mechanisms
List 2 primary systems
Nervous and endocrine systems are primary feedback mechanisms
Maintaining our homeostasis
Transverse plane
Horizontal plane
Divides upper and lower
Horizontal movements
Horizontal abduction
Horizontal adduction
Horizontal abduction
To take away from the midline in the horizontal plane
Horizontal adduction
To move toward the midline in the horizontal plane
Oblique plane
Some combination of 2 other planes
At some diagonal slice/motion
Abdominopelvic quadrants
Horizontally and vertically at the belly button
Right upper quadrant
