Nervous Tissue

2 DIVISIONS OF THE NERVOUS SYSTEM

• Central Nervous System and Peripheral Nervous System
• Motor Nervous System and Sensory Nervous System
• Sympathetic Nervous System and Parasympathetic Nervous System
• Autonomic Nervous System and Somatic Nervous System

WHAT IS AFFERENT

• Nerves that carry signals from the sensory organs to the central nervous system.
• Nerves that carry signals from the central nervous system to the sensory organs.

what is the 2 subdivisions of PNS?

• central nervous system and peripheral nervous system
• somatic nervous system and autonomic nervous system
• sympathetic nervous system and parasympathetic nervous system
• voluntary nervous system and involuntary nervous system

What is efferent?

• Flow of information from the central nervous system to the peripheral nervous system.
• Flow of information from the peripheral nervous system to the central nervous system.
• carries out commands from CNS to muscles, glands and adipose tissue

• Flow of information from the peripheral nervous system to the autonomic nervous system.

what is the three anatomical divisions

• Somatic Nervous System

  Autonomic Nervous System

  Enteric Nervous System

• head, trunk, and limbs
• upper body, lower body, and middle body
• front, back, and sides

What is the somatic nervous system?

• The somatic nervous system is responsible for involuntary movements.
• The somatic nervous system is a part of the central nervous system.
• The somatic nervous system controls sensory information from the brain to the body.
• The somatic nervous system is a part of the peripheral nervous system that controls voluntary movements and sensory information from the body to the central nervous system. Via skeletal muscle

What is the autonomic nervous system?

• The autonomic nervous system is a division of the peripheral nervous system that controls involuntary bodily functions.
• The autonomic nervous system is only found in animals.
• The autonomic nervous system is a division of the central nervous system.
• The autonomic nervous system is responsible for conscious bodily functions.

what is enteric nervous system

• The enteric nervous system is a division of the autonomic nervous system that controls the gastrointestinal system.
• The enteric nervous system is a type of sensory system that controls vision.
• The enteric nervous system is responsible for controlling the respiratory system.
• The enteric nervous system is a part of the central nervous system.

what are the major regions of the neuron

• cell body, dendrites, axon
• nucleus, cytoplasm, cell membrane
• soma, synapse, myelin sheath
• axon terminal, Schwann cells, neurotransmitters

What is dendrites

• Branch-like structures on a neuron that receive signals from other neurons
• Thin, tube-like structures on a neuron that protect the cell body
• Small, round structures on a neuron that store neurotransmitters
• Long, thread-like structures on a neuron that transmit signals to other neurons
