Document Summary
The bronchial arteries/vein from the thoracic vessels supply the structural components of the lungs. Q: an organ that acts like a filter is the: Know the muscle that is used in taking air into the lungs (diaphragm) Comprised of conductive (nerve) and support (neurogia) cells. Structured to facilitate and maximize impulse conduction inside and outside of cns. Neuroglia support nerve cells and contribute to efficient signal transmission. Brain: receives sensory input from the spinal cord as well as from its own nerves processing of sensory inputs and initiating appropriate motor output. Spinal cord: conducts sensory info from the peripheral nervous sytem to the brain conducts motor info from the brain to various effectors: skeletal muscles, cardiac muscles, smooth muscles, glands. Sensory organs: brain, vision, audition body surface(somatosensation), tongue, nostrils. Know that there are four types of neuron in the body. Sensory neuron: carries info from the pns to the cns. Motor neuron: carries motor commands from cns to effectors.
