coracoclavicular ligament – potent band of connective tissue that anchors the coracoid technique of the scapula into the lateral clavicle; offers crucial oblique assistance with the acromioclavicular joint.

antidiuretic hormone (ADH) – hypothalamic hormone that may be stored via the posterior pituitary and that indicators the kidneys to reabsorb h2o.

bronchial artery – systemic department from your aorta that provides oxygenated blood to the lungs Besides the pulmonary circuit.

activation gate – Component of the voltage-gated Na+ channel that opens if the membrane voltage reaches threshold.

costal side – web site over the lateral sides of the thoracic vertebra for articulation with The top of the rib.

axon – single technique of the neuron that carries an electrical signal (action possible) from the cell body towards a focus on cell.

alar plate – developmental location of the spinal cord that gives rise into the posterior horn on the grey matter.
