Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Mass of cell bodies of sensory neurons near the spinal cord
A
Dorsal Root Ganglion
B
Ventral Root Ganglion
C
Efferent Neuron
D
Afferent Neuron
Explanation: 

Detailed explanation-1: -They are found in the posterior (dorsal) root of spinal nerves, following the emergence of the dorsal root, that emerges from the intervertebral neural foramina. contain clusters of sensory neuron cell bodies which transmit messages relating to pain, touch, and temperature from the PNS, towards the CNS.

Detailed explanation-2: -The dorsal root ganglion, more recently referred to as the spinal ganglion, is a collection of neuronal cell bodies of sensory neurons. It is the most common type of sensory ganglion in the human body. Each cell body in the ganglion belongs to what is considered to be a pseudounipolar neuron.

Detailed explanation-3: -1: Spinal nerves: Spinal nerves contain both sensory and motor axons. The cell bodies of sensory neurons are located in dorsal root ganglia.

Detailed explanation-4: -The dorsal root ganglia (DRGs) are located in the peripheral nervous system (PNS), between the dorsal horn of the spinal cord and the peripheral nerve terminals, and contain various cell types such as satellite glial cells, endothelial cells, macrophages and primary sensory neurons.

Detailed explanation-5: -(a) The dorsal root ganglion of the spinal cord contains cell bodies of (motor/sensory/intermediate) neurons. (b) The cerebellum is the part of the brain which is responsible for. (i) conducting reflexes in the body. (ii) maintaining posture and equilibrium.
