Cuz carbon atoms bond with other carbon atoms to form long chains
Axons of the spinal nerve that innervate the ventrolateral body surface, structures of the body wall, and limbs make up the Ventral ramus.
The anterior portion of a spinal nerve is known as the ventral ramus. Shortly after a spinal nerve exits the intervertebral foramen, it branches into the dorsal ramus, the ventral ramus, and the ramus communicans. These contain information that is both sensory and motor.
The sensory and motor fibres that innervate the muscles, joints, and skin of the lateral and ventral body walls as well as the extremities are carried by the spinal nerves' ventral ramus. They continue to be separate from one another throughout the thoracic region and each innervates a small section of muscle and skin along the sides, chest, ribs, and abdominal wall.

Okay so, the mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix. The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur.
Hope that helps (:

Explanation:
Small, electron-lucent vesicles known as synaptic vesicles (SVs) are grouped at presynaptic terminals. They hold neurotransmitters and exocytosis, which is stimulated by calcium, releases them. After exocytosis, SVs are formed locally at the terminals.
- From the presynaptic cell with synaptic vesicles to the postsynaptic cell with neurotransmitter receptors, a signal always moves in one direction across the chemical synapse.
- The correct routing of nerve signals throughout the body is guaranteed by this one-way communication.
- A signal is transmitted from one neuron—the presynaptic, or sending, neuron—to another neuron—the postsynaptic, or receiving, neuron—at the synapse, increasing or decreasing the likelihood that the postsynaptic neuron will fire its own action potential.
- The stimulation causes a sensory neuron to go into an action potential, which alters the motor neuron's potential.
- Excitatory because it tends to depolarize the cell, this potential is known as an excitatory postsynaptic potential (EPSP).
