Functional Anatomy and Training Instructions Flashcards
Bone disease which causes skeletal structures to become brittle and fragile, often leading to fractures and disability.
Osteoporosis
Skeleton consists of two segments, what are they?
axial and appendicular
Transverse cartilage plates located near the end of long bones are responsible for increases in vertical growth during childhood/adolescence.
Epiphyseal plate
What are the four bone types called? Simple names
Short, Long, Flat, and Irregular
The intersection of two bones is called?
Joints
Uses synovial fluid to reduce frictional stresses and allow for considerable movement between the associated articulating bones.
Synovial Joint
Hold bones together at joints.
Ligaments
Connects muscles to bones
Tendons
Fibrous connective tissue that encapsulates full muscles as well as bundles of fibers; provides the muscle’s shape and regulates tension/transfer of force across joints
Muscle Fascia
Nerve information is carried via
Action Potential
Motor neuron and all the muscle fibers it innervates
Motor Unit
__________ is dictated by motor unit firing rate, recruitment and synchronicity.
Force Production
Muscle that contracts/shortens during a given exercise (e.g., biceps during a curl) *Not a contraction term
Agonist
Muscle that relaxes and lengthens during a given exercise to accommodate contraction of the agonist (e.g., triceps during a biceps curl) *Not a contraction term
Antagonist
Tension remains constant while joint angles change. (Muscle Contraction)
Isotonic
Occurs during the acceleration phase of a lift as the muscle shortens. (Muscle Contraction)
Concentric
Occurs during the deceleration phase of a lift as the muscle lengthens. (Muscle Contraction)
Eccentric
Tension is created but no joint angle changes; common in stabilizers. (Muscle Contraction)
Isometric
Involves a constant speed of movement; requires specialized rehab equipment. (Muscle Contraction)
Isokinetic
Splits the body into left and right halves; includes exercises that require forward-backward movement.
EX. Lunge
Sagittal Plan
Splits the body into front and back halves; includes exercises that require side-to-side movement.
EX. Lateral raises
Frontal Plan
Splits the body into top and bottom halves; includes exercises that require rotation.
EX. Oblique Twists
Transverse Plan
The median plane of the body.
Midline
Located before or in front.
Anterior
Located behind or toward the rear.
Posterior
Situated nearest to point of attachment or origin.
Proximal
Situated farthest from point of attachment or origin
Distal
Above another given structure
Superior
Below another given structure.
Inferior
Toward the midline or center of the body.
Medial
Situated or extending away from the midline of the body.
Lateral
On, or relating too, the same side of the body.
