A-level Biology/Transport/multicellular plants Root hair to xylem [edit]. From the root hair cells, water again moves down a concentration gradient toward the xylem, and can take one of three paths-apoplast and symplast and vacuolar. The apoplast pathway is where water takes a route going from cell wall to cell wall, not entering the cytoplasm at any point.

Hair cell For hair cells on the external skin, see Hair follicle. For algal 'hair cells', see Trichocyte (disambiguation). See also: Stereocilia (inner ear) Hair cells are the sensory receptors of both the auditory system and the vestibular system in the ears of all vertebrates. Through mechanotransduction, hair cells detect movement in their environment. In mammals, the auditory hair cells are located within the spiral organ of Corti on the thin basilar membrane in the cochlea of the inner ear.

- Several specializations make human hair cells responsive to various forms of mechanical stimulation. Hair cells in the Organ of Corti in the cochlea of the ear respond to sound. Hair cells in the cristae ampullares in the semicircular ducts respond to angular acceleration (rotation of the head). Hair cells in the maculae of the saccule and the utricle respond to linear acceleration (gravity). (See the chapter on Vestibular System: Structure and Function).

- However, the process varies with the kind of cell. Somatic , or body cells, such as those that make up skin, hair, and muscle, are duplicated by mitosis . The sex cells, sperm and ova, are produced by meiosis in special tissues of male testes and female ovaries . Since the vast majority of our cells are somatic, mitosis is the most common form of cell replication.

Can I Eat Grapefruit Right Before I Go to Sleep? Benefits If you tend to get hungry between dinner and bedtime, the best way to control your weight and your diet is with a low-calorie snack that provides plenty of nutrients. As a citrus fruit, grapefruit is rich in vitamin C, and it also contains a healthy dose of disease-fighting antioxidants.

Hearing and Hair Cells There are two types of hair cells: inner hair cells and outer hair cells. These cells have stereocilia or hairs that stick out. The bottom of these cells are attached to the basilar membrane, and the stereocilia are in contact with the tectorial membrane.

Picture of the Hair Hair is simple in structure, but has important functions in social functioning. Hair is made of a tough protein called keratin. A hair follicle anchors each hair into the skin. The hair bulb forms the base of the hair follicle. In the hair bulb, living cells divide and grow to build the hair shaft. Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life. Hair growth occurs in cycles consisting of three phases: Anagen (growth phase): Most hair is growing at any given time.

Hair Follicle 9. Hair bulb. -. The base of the hair follicle is a bulb-shaped structure called the hair bulb. This includes several layers of different types of cells that extend up through the hair follicle, an indentation called the papilla (of the hair) - see below, and a region of cells called the germinal matrix.10.air follicles are the structures from which hairs emerge from the skin. Each hair is a thread of fused (i.e. attached together), dead, keratinized cells. The two main parts of hairs are: 1  The hair shaft is the visible part of the hair that protrudes through the skin.

Be Part of Ask A Biologist Cilliated columnar cells have their apical (or outside facing) surface covered with many tiny little hairs called cilia. These are used to push mucus and other particles along, making it flow in a specific direction. In addition to these shapes, epithelial cells can be described as being either simple or stratified.

How Cells Divide Asexual reproduction relies on a process called mitosis, in which the nucleus of a cell divides to create two new nuclei, each containing an identical copy of DNA. Mitosis allows the cells in your body to divide and regenerate—your hair to grow, your skin to heal after being wounded.

- The cell division process that produces new cells for growth, repair, and the general replacement of older cells is called mitosis. In this process, a somatic cell divides into two complete new cells that are identical to the original one. Human somatic cells go through the 6 phases of mitosis in 1/2 to 1 1/2 hours, depending on the kind of tissue being duplicated. Six phases of mitosis.

Hair cell Neurons of the auditory or vestibulocochlear nerve (the eighth cranial nerve) innervate cochlear and vestibular hair cells. The neurotransmitter released by hair cells that stimulates the terminal neurites of peripheral axons of the afferent (towards the brain) neurons is thought to be glutamate.

How Our Balance System Works All contain sensory hair cells that are activated by movement of inner ear fluid (endolymph). As the head moves, hair cells in the semicircular canals send nerve impulses to the brain by way of the acoustic nerve. The nerve impulses are processed in the brain to help us know where we are in space or if we are moving.

Integumentary System Hair Follicle.  1  Root sheath extending from the epidermal surface into the dermis.  2  Deep end is expanded forming a hair bulb.  3  A knot of sensory nerve endings (a root hair plexus) wraps around each hair bulb.   Bending a hair stimulates these endings, hence our hairs act as sensitive touch receptors.

Stereocilia (inner ear) Bending the hair cells stretches the tip link, causing an influx of K+ ions and the generation of neural impulses in the VIIIth cranial nerve. Hair cells in the vestibular system are slightly different from those in the auditory system, in that vestibular hair cells have one tallest cilium, termed the kinocilium. Bending the stereocilia toward the kinocilium depolarizes the cell and results in increased afferent activity.

- Somatic cells make up the skin, hair and muscle tissues. They reproduce through a process called mitosis, which is the most common form of cell replication. Mitosis can happen when areas of the body is growing, when older cells are replaced or when an area of the body becomes damaged or injured.

Accessory Structures of the Skin The shape and structure of these layers are, in turn, determined by the shape of the hair follicle. Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface.
