HUMAN ANATOMY EXAM #3100%SOLVED GRADED A+
Which animal has the highest brain to body mass ratio? - Homo Sapiens (Humans)
What are the functions of the Nervous System - 1. Sensory Information
2. Sensory Integration
3. Motor response
What generates and propagates electrical signals, called action potentials in the
Nervous system? - Neurons
What provides support and maintain extracellular environment in the nervous system. -
Glial Cells
Neurons are... - *Basic functional unit of nervous system
*Amitotic
*Highly metabolic
*Longest cells in the body
*Capable of propagating, transmitting electrical impulses
*Communication cells of the nervous system
What are the four parts of the Neuron - -Cell body
-Dendrites
-Axon
-Axon terminal
What does the Dendrites do... - Receive signals and information to the cell body...
What does the Axon do... - Transmits signals and information away from the cell body
What does the Axon terminal do... - It forms synapse at the tip of the axon

-Subdivde into telodendria
What are Axon usually covered with... - Myelin Sheath
What are Nodes of Ranvier - Gaps in the myelin Sheath
What are unipolar neurons.. - One fused axon and dendrite (sensory neurons)
What are bipolar neurons... - One axon and one dendrite (special sensory neurons)
What are Multipolar neurons... - One axon and several dendrites (motor neurons)
Functions of sensory (afferent) neurons - Carry impulses into CNS
Functions of motor (efferent) neurons... - Carry impulses from the CNS
Functions of Interneurons (association) nuerons... - Carry impulses within the CNS
Large, branching cells that form the blood-brain barrier - Astrocytes
Cells with few branches that secrete myelin in the CNS - Oligodendrocytes
Tiny cells with complex branches that are phagocytes of the CNS - Microglia
Ciliated cells that help form choroid plexuses, which secrete, circulate and monitor
cerebrospinal fluid - Ependymal Cells
CSF = - Cerbrospinal fluid
Supports cells that are non conductive in the CNS - Neuroglia
What are the Glial Cells of the CNS... - Astrocytes
Oligodendrocytes
Microglia
Ependymal Cells

Weblike covering enclosing the cerebrospinal fluid - Arachoid
delicate inner vascular membrane that adheres to the CNS - Pia mater
Tough outer covering of the CNS - Dura Mater
