Cranial nerves

Classification of Cranial Nerves and Their Functions

Embark on a journey through the intricacies of the human nervous system as we explore the twelve cranial nerves, each with its own unique classification and vital functions.

Sensory Cranial Nerves

These cranial nerves are messengers of sensation, carrying information from our senses to the brain:

Olfactory Nerve (I): Sense of smell
Optic Nerve (II): Vision

Motor Cranial Nerves

Motor cranial nerves control our muscles and movements:

Oculomotor Nerve (III): Eye movement and pupil dilation
Trochlear Nerve (IV): Eye movement

Mixed Cranial Nerves

Mixed cranial nerves have both sensory and motor functions:

Trigeminal Nerve (V): Chewing, facial sensations
Facial Nerve (VII): Facial expressions, taste

These fascinating cranial nerves weave a complex web of communication, enabling us to experience the world and control our bodies. Each nerve, a testament to the marvels of our biology.

Adrenergic neurotransmitters.

Adrenergic Neurotransmitters and Their Types Adrenergic Neurotransmitters and Their Types Adrenergic neurotransmitters are a crucial part of the human nervous system. They play a vital role in the transmission of signals between nerve cells and various target tissues. These neurotransmitters are derived from the amino acid tyrosine and have a profound impact on physiological responses. Types of Adrenergic Neurotransmitters Adrenergic neurotransmitters can be categorized into two main types: norepinephrine and epinephrine. 1. Norepinephrine Norepinephrine, often referred to as noradrenaline, is a neurotransmitter released by the sympathetic nervous system. It plays a key role in the "fight or flight" response, increasing heart rate, constricting blood vessels, and raising blood pressure. Norepinephrine also affects mood and arousal. 2. Epinephrine Epinephrin...

Myocardial Infraction.

Myocardial Infarction Myocardial Infarction What is Myocardial Infarction? Myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow to a part of the heart muscle is blocked for a prolonged period. This lack of blood flow causes damage or death to the heart muscle. The primary cause of myocardial infarction is the buildup of fatty deposits, or atherosclerosis, in the coronary arteries. Symptoms of Myocardial Infarction The symptoms of a myocardial infarction can vary from person to person. Common symptoms include: Chest pain or discomfort Pain in the neck, jaw, or back Pain or discomfort in the arms or shoulders Shortness of breath Nausea or vomiting Cold sweat Feeling lightheaded or dizzy It's important to note that not all people experience che...
