What else can I help you with?
Collateral ganglia contain neurons that innervate tissues and organs in which cavity?
Collateral ganglia contain neurons that primarily innervate tissues and organs in the abdominal and pelvic cavities. These ganglia are part of the autonomic nervous system, specifically the sympathetic division, and they help regulate functions such as digestion and urinary processes by connecting to various target organs.
Is Autonomic ganglia are motor ganglia only?
No, autonomic ganglia can contain both motor and sensory neurons. Motor neurons in autonomic ganglia innervate smooth muscle, cardiac muscle, and glands, while sensory neurons can detect stimuli within the autonomic nervous system.
Who do preganglionic neurons synapse with?
Preganglionic neurons synapse with postganglionic neurons in the autonomic nervous system. These synapses occur in ganglia, which are clusters of nerve cell bodies located outside the central nervous system. In the sympathetic division, preganglionic neurons typically synapse in sympathetic ganglia near the spinal cord, while in the parasympathetic division, they synapse in ganglia located close to or within the target organs. This synaptic connection is crucial for transmitting signals that regulate involuntary bodily functions.
Are collections of neuron cell bodies associated with nerves in the PNS?
Yes, collections of neuron cell bodies associated with nerves in the peripheral nervous system (PNS) are known as ganglia. Ganglia can contain cell bodies of sensory neurons (dorsal root ganglia) or autonomic neurons (autonomic ganglia) that help relay information to and from the central nervous system.
Does the ganglia contain sensory neurons?
No, the ganglia are clusters of nerve cell bodies located outside of the central nervous system. They primarily contain motor neurons that transmit signals from the central nervous system to muscles and glands for motor control. Sensory neurons transmit signals from sensory organs to the central nervous system for processing.
What are neurons in the ganglia?
a huge one

What are collections of neurons?
nuclei in the CNS, ganglia in the PNS
Why ganglia absent in ventral roots?
the ganglia sends information and the spinal nerves are dorsal which receives information. you would not have the one the sends information in the nerve that receives information you would be wasting resources
Are collections of neuron cell bodies associated with nerves in the PNS?
Yes, collections of neuron cell bodies associated with nerves in the peripheral nervous system (PNS) are known as ganglia. Ganglia can contain cell bodies of sensory neurons (dorsal root ganglia) or autonomic neurons (autonomic ganglia) that help relay information to and from the central nervous system.
What is a knot-like swelling in a nerve where the cell bodies of neurons are concentrated?
Paravertbral ganglia (aka sympathetic trunk ganglia)
Do jellyfish have ganglia?
no, just a nerve net which is a collection of separate neurons
Does the ganglia contain sensory neurons?
No, the ganglia are clusters of nerve cell bodies located outside of the central nervous system. They primarily contain motor neurons that transmit signals from the central nervous system to muscles and glands for motor control. Sensory neurons transmit signals from sensory organs to the central nervous system for processing.
Clusters of neurons cell bodies are called?
Clusters of neurons cell bodies are called ganglia in the peripheral nervous system and nuclei in the central nervous system. Ganglia contain the cell bodies of sensory or motor neurons, while nuclei contain cell bodies of interneurons or projection neurons.
