Exam 3 part two Flashcards
What are the three major components of transmission
Sensory receptors –> Process and integration –> Motor output
What organs take place in the central nervous system
The brain and spinal column
What organs take place in peripheral nervous system
Cranial and spinal nerves
What is the process of transducing information
Receptors convert info to impulses, then the cns integrates the signals, then brough together to create memory, feeling, etc. then a conscious or subconscious action are made
What are the 5 types of receptors
Pain, thermoreceptor, chemoreceptor, photoreceptor.mechanorecptor
What are the subdivisions of the motor portion of the pns

The types of neurons
Unipolar, bipolar, and multipolar

What are the major endocrine glands(7)
Petuitary, thyroid, parathyroid, Adrenal, Pancreas, Thymus, ovaries and testes.
What are the effects or actions of hormones?
Effect metabolic process,deliver messages by binding their receptors on target cell,
What determines the strength of response of a hormone.
Number of receptors
What is up regulation?
Increase of receptors on target cell, in response to decrease of hormone
What is down regulation?
A decrease of receptors due to an increase in hormone level.
Types of neuroglia
Astrocytes
Microglia
Ependyma
Oligodendrocytes
