Spaces around the meninges

epidural space: is outside the dura mater but inside the bony coverings of the spinal cord. Subdural space: between the dura mater and arachnoid mater. Subarachnoid space: under the arachnoid and outside the pia mater (CSF).

reticular activating system (RAS)

centers in the brainstem’s reticular formation that receive impulses from the spinal cord and then send them to the thalamus and from the thalamus to all parts of the cerebral cortex

The limbic system (emotional brain)

make us experience many kinds of emotions such as anger, fear, joy, sadness, surprise, and disgust.

they supply the diaphragm muscle, Contraction of the diaphragm allows inspiration, and relaxation of the diaphragm, and expiration. (from cervical plexus)

cranial nerves (mixed: motor/sensory)

trigeminal, facial, glossopharyngeal, and vagus nerve

free nerve endings that serve as the primary sensory receptors for pain, nerve fibers carry pain impulses from nociceptors to the brain, divided into two types acute or fast (A) pain fibers and chronic or slow (B) pain fibers.

consists of two separate glands, adenohypophysis- anterior pituitary gland, and the neurohypophysis-posterior pituitary gland.

parathyroid hormone (PTH)

acts on bone and kidney cells by increasing the release of calcium into the blood, calcium homeostasis

functions, including defense, hematopoiesis, RBC and platelet destruction, serves as a reservoir for blood.
