Anatomically Speaking
Anatomical Position
The skeletal system has these two major divisions
Axial and Appendicular
The functional unit of the nervous system is this.
Neuron
Send Chemical / Hormonal Signals
How any of each vertebra are there?
Cervical - 7
Thoracic - 12
Lumbar - 5
The three body planes are these.
Frontal, Sagittal, Transverse.
What is the the name of the joint that attaches the pectoral girdle to the axial skeleton?
Sternoclavicular joint
The electrical and chemical signals that transmit information throughout the body are these.
Action Potential and Synapse.
This gland is responsible for regulating other glands.
Pituitary Gland
What is rickets and what causes it?
Bone deterioration due to calcium deficiency
This anatomical region refers to the arm/upper limb.
This type of joint allows for some flexibility but does not provide full range of motion.
Cartilaginous.
This covering is not found on all nerve cells but improves conduction.
Myelin Sheath.
This type of stimulus occurs with changes to ion concentrations it the blood.
Humoral Stimulus
Describe the difference between efferent and afferent nerves.
Efferent = transmits signals from the brain
Afferent = transmits signals to the brain.
The nine regions of the abdominopelvic cavity are these.
Left and right hypochondriac, epigastric
Left and right lumbar, umbilical
Left and right iliac, hypogastric
These bony bumps reside on the superior portion of the thigh bone.
Trochanters
The period must pass in order for another signal to be sent.
Refractory Period
This hormone is released when blood sugar is low
Glucagon
What makes a high surface area to volume ration desireable for cells?
Improves efficiency for cellular exchange.
The Dorsal Cavity contains these structures
Brain and Spinal Cord
This tissue is responsible for providing nutrients to growing bones.
Periosteum
When the action potential is repolarizing, where are the Na+ and K+ ions?
Sodium ions are inside the cell, Potassium ions are moving out the cell.
This type of hormone can directly activate genes.
