nerve cell, neuron - a cell that is specialized to conduct nerve impulses fasciculus, fiber bundle, fibre bundle, fascicle - a bundle of fibers (especially nerve fibers) central nervous system, CNS, systema nervosum centrale - the portion of the vertebrate nervous system consisting of the brain...
The size and shape of these neurons vary widely, but the structural plan always includes certain elements (Fig. 1-1): a cell body, or soma , and the processes from this cell body, namely an axon (neurite), and usually several dendrites . The neuron diagrammed in Fig. 1-1 has one ...
The nature of each synapse—whether excitatory or inhibitory—is determined by the neurotransmitter released from the presynaptic terminal and the specific receptors present on the postsynaptic membrane. Each neuron synthesizes a particular neurotransmitter for use at its synapses, leading to classifications...
Stretch of a neuron Light Sound Temperature change, hot or cold Neurotransmitters or chemical messengers These stimuli result in ion channels within the cell to open and release one or more of the ions through the cellular membrane and into the synaptic space, which changes the membrane potential...
Step-by-Step Text Solution:1. Understand the Components: Before drawing, familiarize yourself with the key components of the human fetus and the uterus. The main parts include the fetus itself, the amniotic sac
any wiring diagram that guarantees the connection profile of unimodal cortex would be as good as any other in maintaining normal brain function. However, abundant empirical evidence indicates that structural connections exhibit a high level of consistency and specificity21,22. Third, the structure and...
Our skin is an impressive organ that has many useful functions. It reduces water loss, fights infections, helps regulate our temperature, and makes vitamin D.

This diagram shows the epineurium that is a connective sheath that surrounds the entire nerve and perineurium that is present between nerve fibers bundles. Perineurium Perineuriumrepresent dense irregular connective tissue layers between bundles of nerve fibers. The innermost layer of the perineuri...
