• A sagittal plane that lies exactly in the midline
Transverse Plane - ANS• a.k.a. horizontal plane
• Runs horizontally from right to left
• Divides the body into superior and inferior parts
• A transverse section is also called a cross section
Dorsal Body Cavity - ANS• Protects the fragile nervous system organs (brain & spinal cord)
• Has two subdivisions: cranial & vertebral/spinal cavities
,Ventral Body Cavity - ANS• More anterior and larger of the closed body cavities
• Two major subdivisions: thoracic & abdominopelvic cavities
• Houses internal organs collectively called viscera, or visceral organs
Cranial Cavity - ANS• In the skull; encases the brain
• Continuous with the vertebral/spinal cavity
Vertebral/Spinal Cavity - ANS• Runs within the bony vertebral column
• Encloses the spinal cord
Body Cavities - ANS• Two sets of internal body cavities: dorsal & ventral body cavities
• Closed to the outside
• Provide degrees of protection to organs contained within
• Dorsal/ventral differ in mode of embryonic dev. & lining membranes
• Not widely used anatomical reference; a useful learning concept
Anatomy - ANS• The structure of body parts and their relationships to one another
Dorsiflexion - ANS• Lifting the foot so that its superior surface approaches the shin
• Corresponds to wrist extension
Plantarflexion - ANS• Depressing the foot (pointing the toes)
• Corresponds to wrist flexion
Inversion - ANS• Sole of the foot turns medially
Eversion - ANS• Sole of the foot faces laterally
Protraction - ANS• Non angular anterior movements in a transverse plane
• The mandible is protracted when you jut out your jaw
Retraction - ANS• Non angular posterior movements in a transverse plane
• The mandible is retracted when you bring it back from protraction
Elevation - ANS• Lifting a body part superiorly
• Example, the scapulae are elevated when you shrug your shoulders
Depression - ANS• Moving the elevated part inferiorly
• During chewing, the mandible is alternately elevated & depressed
Opposition - ANS• Action of touching thumb to tips of other fingers on same hand
• Occurs at saddle joint between metacarpal I & trapezium
Prime Mover - ANS• Muscle that has major responsibility for producing a specific mvmt
,• a.k.a. agonist or "leader"
Antagonist - ANS• Mm that oppose, or reverse, a movement; "against the leaders"
• Help regulate action of prime movers by contracting to provide resistance
• Located on opposite sides of the joint across which they act
Synergist - ANS• syn = together, erg = work
• Help prime movers by: adding extra force to the same movement
• Reducing undesirable or unnecessary movements that might occur
Fixator - ANS• Muscles that help maintain upright posture
• Type of synergist; when mm immobilizes a bone or muscle origin
• Provides the prime mover with a stable base on which to act
Flexion - ANS• Bending movement, usually along the sagittal plane
• Decreases the angle of the joint; brings articulating bones together
Extension - ANS• Involves movement along the sagittal plane
• Increases the angle between the articulating bones
• Typically straightens a flexed limb or body part
• Continuing such mvmts beyond anatomical position is hyperextension
Abduction - ANS• "moving away"
• Mvmt of limb away from midline/median, along frontal plane
• Raising the arm or thigh laterally is an example
• For fingers/toes: spreading them apart; "midline" is the longest digit
Acetabulum - ANS• Cuplike cavity on lateral surface of the hip bone that receives the femur
• Faces inferolaterally, w/the acetabulur notch directly inferiorly
• Formed by all three bones forming the hip bone
Adduction - ANS• "moving toward"
• Movement of a limb toward the body midline
• In the case of the digits, toward the midline of the hand or foot
Amphiarthrosis - ANS• A slightly movable joint
Anastomosis - ANS• A union or joining of nerves, blood vessels, or lymphatics
Angular Movement - ANS• Increase or decrease the angle b/w two bones
• May occur in any plane of the body
• Flexion, extension, hyperextension, ab- & ad-duction, circumduction
Aorta - ANS• Major systemic artery
, • Arises from the left ventricle of the heart
Arteries - ANS• Blood vessels that conduct blood away from the heart and into circulation
Aponeurosis - ANS• Fibrous or membranous sheet connecting a muscle & part it moves
• Flat broad CT sheath attaching muscle to bone
Atria - ANS• The two superior receiving chambers of the heart
Atrioventricular (AV) Node - ANS• Specialized mass of conducting cells
• Located at the atrioventricular jct. in the heart
Atrioventricular (AV) Valve - ANS• Prevents backflow into the atrium when the connected
ventricle is contracting
Autonomic Nervous System - ANS• a.k.a. involuntary or visceral motor system
• Efferent division of peripheral nervous system
• Innervates cardiac & smooth muscles and glands
Biaxial Movement - ANS• Movement in two planes
Circumduction - ANS• Moving a limb so that it describes a cone;
• circum = around; duco = to draw
• Distal end of the limb moves in a circle
• Point of the cone is stationary
• Consists of flexion, abduction, extension, & adduction in succession
• Thumb: extension, adduction, flexion, abduction
CN I: Olfactory - ANS• Fxn: Purely sensory; carry afferent impulses for sense of smell
• CT: Client asked to sniff aromatic substances
• Injury: Partial/total loss of smell; possibly caused by # of ethmoid
CN II: Optic - ANS• Fxn: Purely sensory; carry afferent impulses for vision
• CT: Vision and visual field are determined w/eye chart
• Injury: Results in blindness in eye served by nerve"
CN III: Oculomotor - ANS• "eye mover"
• Supplies four of the six extrinsic mm. moving the eyeball in the orbit
• CT: Pupils are examined for size, shape and equality
CN IV: Trochlear - ANS• Innervates an extrinsic eye muscle
