Originating from the base Berry - A fleshy indehisent pulpy, succulent fruit with immersed seeds Bipinnate - Doubly or twice pinnate (Bipinnately compound) Blade - The broad, flat part of a leaf Bract - Modified leaf, generally associated with an inflorescence Bracts may resemble normal leaves or be reduced and scalelike in appearance; they are sometimes large and brightly colored
In plants that form rosettes, the basal leaves are those that arise directly from the crown of the plant, and which often differ from leaves arising from the stem
In a phylogenetic tree, being a group, or member of a group, which diverged early
especially of leaves; located at the base of a plant or stem; especially arising directly from the root or rootstock or a root-like stem; "basal placentation"; "radical leaves"
A collection of student texts and workbooks, teacher's manuals, and supplemental materials for developmental instruction; used chiefly in elementary and middle school grades; i e , a basal reading program
serving as or forming a base; "the painter applied a base coat followed by two finishing coats
{i} BCC, common form of skin cancer malignant tumor (usually doesn't metastasizes) in which the cancer cells look like the basal cells of the epidermis and is found on the face and neck where the skin is exposed to ultraviolet sunlight (it appears as a bleeding or scabbing sore that does not heal)
A cellular organelle associated with the formation of cilia and flagella and similar to the centriole in structure. Also called basal granule, kinetosome
natural family planning in which the fertile period of the woman's menstrual cycle is inferred by noting the rise in basal body temperature that typically occurs with ovulation
An interconnected group of three forebrain nuclei involved in motor control The three nuclei are the caudate nucleus, the putamen, and the globus pallidus
Groups of cells in the grey matter of each half of the brain which coordinate automatic movements It comprises various specialised groups of cells, or nuclei, such as the globus pallidus and the substantia nigra
A group of nerve cells located at the base of the brain It is composed of the putamen, caudate, globus pallidus, and substantia nigra These nerve cells participate in the regulation of motor performance (Singular form: basal ganglion )
Clusters of neurons that lie beneath the hemispheres of the cerebrum, they are associated with "initiation, smoothness, and precision of movement, and are responsible for the automatic movements we make without thinking "(Restak, 16) For more information, see these links
a collective name for a set of structures located around the thalamus, also known as the putamen and globus pallidus, that are part of the motor control mechanism of the brain
a collection of clusters deep within the cerebrum which plays an important role in producing smooth continous muscular actions and starting and stopping movement
The large, complex set of brain structures involved in generating movements, in some cognitive functions, and in some emotional and motivational activities The basal ganglia and the cerebral cortex work together to refine movements, thoughts, and feelings
involved primarily in the control of motor activity, and deficits in this area are significant in movement disorders such as parkinsonianism and Huntingtons chorea Components of the basal ganglia include the caudate nucleus, putamen, globus pallidus, lentiform nucleus, substantia nigra and others
any of several masses of subcortical gray matter at the base of each cerebral hemisphere that seem to be involved in the regulation of voluntary movement
Any of several masses of gray matter embedded in the cerebral hemispheres that are involved in the regulation of voluntary movement. Also called basal nucleus
A proteoglycan and glycoprotein sheet secreted by cells to form the extracellular matrix The basal lamina, also called the basement membrane, is a three-layer structure that influences cell polarity, differentiation, and migration
a term used to describe the different layers which make up the basement membrane These different layers of the basement membrane, the lamina lucida and lamina densa are only visible with electron microscopy Into the lamina dense collagen fibres of the lamina propria are anchored And on the epithelial side are anchored bundles of tonofilaments from the hemi-desmosomes which anchor the basal epithelial cells to the basement membrane
The rate at which energy is used by an organism at complete rest, measured in humans by the heat given off per unit time, and expressed as the calories released per kilogram of body weight or per square meter of body surface per hour
The minimum amount of energy required to maintain vital functions in an organism at complete rest, measured by the basal metabolic rate in a fasting individual who is awake and resting in a comfortably warm environment
