Tissues are made of cells that share morphological features to achieve specific functions within the body. They are 4 types of tissue in our body: 1. What Is a Connective Tissue? Connective tissue provides structure, support, protection, and connection to other tissues and organs of the body [1]. 1.1. What Are the 3 Types of…
Skin diseases are associated with conditions that affect the structure or function of the skin, causing irritation, clogging, or damage. Although there are many skin diseases, the following are the most common: Acne is the most common skin condition in the United States and affects up to 50 million Americans annually, while 1 in 10…
Cardiovascular diseases are diseases that affect the normal function of the heart and blood vessel circulation. The most common cardiovascular diseases include: Every 36 seconds, one person dies from cardiovascular disease and 659,000 individuals die from heart diseases in the United States [1]. Heart disease is the leading cause of death in the United States….
Joint diseases include any pathology affecting an articulation or more, resulting in inflammation and degeneration of the articular tissues. The following disorders are the most common: Joint diseases or arthropathies can be due to joint trauma, autoimmunity, infections, metabolic, or heredity. 1. What is joint Made of? Joints or articulations connect the bones of the…
Bone diseases are characterized by alterations in the formation, mineralization, and resorption of the bone tissue. The following are the most common diseases of the bone tissue: 1. What is Bone Made of? The bone is a hard connective tissue (support and connect tissues) that contains a honey-comb shaped structure made of a mineralized matrix…
The body temperature is controlled by a small area of the brain known as the hypothalamus which maintains the body’s temperature through thermoregulation. The hypothalamus works like a thermostat for the body and maintains the temperature in the range of 97.7-99.5 °F (36.5-37.5 °C) [1]. Hypothermia is when the body temperature is lower than 95…
The sense of touch is controlled by the somatosensory cortex located in a region of the parietal lobe known as the post-central gyrus that is found on the middle top of the brain. In addition to its role in controlling touch, the somatosensory cortex is also involved in sensing temperature, pain, and body position and…
Sounds are detected by the ears in the form of vibrations and transformed into nerve impulses by specialized neurons which then transmit the sound (auditory) information to the auditory cortex for processing. The auditory cortex is located in the temporal lobe of the brain. The transmission of the auditory information through neurons to the auditory…
Vision information relayed from the eyes retinas is processed by the visual cortex which is a part of the occipital lobe found at the back of the brain. There are two parts of the visual cortex according to the two brain hemispheres: the right visual cortex and the left visual cortex. The right visual cortex…
The part of the brain responsible for taste (gustation) is known as the gustatory cortex or primary gustatory cortex. It is involved in the perception and differentiation between different types of taste [1]. However, there are several steps before taste information reaches the gustatory cortex for processing: The papillae contain taste buds that are specialized…
