There are other differences too between nerve and vein in terms of their structure, functions, etc. A nerve is made up of several thousand nerve fibers enclosed in a connective outer sheath. Nerves are connected via nerve cells known as neurons.
A nerve fiber is either a long axon or dendrite of a neuron. Depending on the presence or absence of myelin sheath, there are two types of nerve fibers; namely, myelinated nerve fibers and nonmyelinated nerve fibers. Not all nerves are interconnected. Nerve network starts mainly from the brain and spinal cord.
Blood vessels which transport deoxygenated blood to the heart except the pulmonary vein which goes from the lungs to the heart and carry oxygenated blood. Femoral nerve — Innervates the anterior compartment of the thigh, and provides sensory branches for the leg and foot.
Difference between Nerve and Vein. Key Difference: Veins are large return vessels of the body which carry blood to the heart. They can be considered as blood return counterparts of arteries. They transmit information between periphery and central nervous system. Comparison between Nerve and Vein: Nerve Vein Definition Nerves are bundles of axons constituting the peripheral nervous system. Types Afferent, efferent and mixed nerves — some nerves work as one way highways.
Some nerves carry signals only from the central nervous system. Some nerves work in 2 way street styles Cranial Nerves — are 12 pairs of nerves which emerge directly from brain and the brainstem Spinal nerves — refers to any of the paired peripheral nerves which arises from the spinal cord Pulmonary veins — transport oxygen rich blood from lungs to the left portion of heart so that it can be pumped to the body Superior and Inferior carvae veins — they carry oxygen poor blood from the body to the heart Associated with the Nervous System Blood Circulatory System Contents of the femoral triangle Femoral nerve — Innervates the anterior compartment of the thigh, and provides sensory branches for the leg and foot.
Femoral vein — The great saphenous vein drains into the femoral vein within the triangle. Veins need valves to keep the blood flowing toward the heart. Theses valves are particularly important in the legs and arms. They fight gravity to prevent the backflow of blood.
The cardiovascular system is a closed system of vessels called arteries, veins, and capillaries. The cardiovascular system keeps a continuous and controlled movement of blood that delivers nutrients and oxygen to every cell in the body.
It does this through thousands of miles of capillaries between the arteries and the veins. Nutrients and oxygen are delivered to every cell in your body through a circulatory system.
The heart pumps oxygenated blood to your cells through arteries. It pumps oxygen-depleted blood away from your cells through veins. If you have chronic health conditions, your blood oxygen level may fall outside of the normal range.
This includes people with asthma, heart disease…. Figure 2: Human Venous System. The wall of a vein is made up of three types of tissue layers: tunica adventitia, tunica media, and tunica intima.
Tunica adventitia is the outermost layer of the vein, and it is made up of connective tissues. Tunica media is the middle layer of the vein, which is made up of smooth muscles. Tunica intima is the inner layer of a vein. It is made up of a smooth endothelial layer. Each vein is composed of valves in the lumen to prevent the backward movement of blood. The major driving force of the blood inside a vein is the contraction of muscles near to a vein. The structure of a vein is shown in figure 3.
Systemic, pulmonary, Superficial, and deep veins are the four types of veins in the body. Systemic veins drain deoxygenated blood from the body to the heart.
Superficial veins occur near the skin. Deep veins occur within muscles and tissues. Pulmonary veins drain oxygenated blood from the lungs to the heart.
