5 and 8.2 Flashcards
Osteology
Study of bones
3 types of bones
Long
Flat
Irregular
Skeletal system
Provides strength and support, framework for body
Muscles
Produce movement, contract when stimulated by nervous system
Myology
Study of structure, function, and diseases of muscles
Muscular functions
Movement
Attachment
Protection
Shape
3 types of muscle tissue
Striated
Non-striated
Cardiac
Origin
Fixed portion, attached to bones and fixed muscle
Belly
Midsection, between two attached sections
Insertion
Portion of muscle joined to movable attachments - bones, movable muscles, skin
Tendons
Bands of fibrous tissue that attach the muscle to the bones, allowing bones to move
Ligaments
Dense strong bands of fibrous tissue that connects bones to each other
Scalp and face muscles
Muscles affected by massage are manipulated from insertion attachment to origin attachment
Light facial massage should follow muscle line
Epicranius
Broad muscle that covers the scalp, formed by two muscles joined by aponeurosis tendon
Plasma
Fluid part, carries RBC, WBC, and platelets, 90% water
Arteries
Carry blood away from heart, branching vessels, pure blood
Veins
Carry blood from capillaries to heart, impure blood
Capillaries
Take nutrients and oxygen from arteries to cells, take waste from cells to veins
Lymph
Colorless, nourishes parts not reached by blood
Lymph nodes
Glands that filter out toxins, over 100 in body, swollen means infected
Neurology
Study of nervous system, coordinates and controls body operation
Cerebrum
Mental activity, upper front of cranium
Cerebellum
Muscle movement, occipital area below cerebrum
Pons
Connects other parts of brain to spinal column, below cerebrum and in front of cerebellum
Medulla oblongata
Connects other parts of brain to spinal column, below pons
Brain subsystems
Central
Peripheral
Autonomic
Central nervous system
Brain, spinal cord, spinal and cranial nerves, voluntary and involuntary actions
Peripheral nervous system
Sensory and motor nerves from brain and spinal cord to voluntary music and surface of skin, carries sensory information to brain
Sympathetic and parasympathetic
Homeostasis
State of balance
Dendrites
Receive messages
Synapses
Nerve impulses pass
Pharynx
Passage to stomach or lungs
Esophagus
Passage between pharynx and stomach
