What is the embryonic origin of secondary mesoenchyme cells in equinoderms?
The embryonic origin of secondary mesenchyme cells in echinoderms is from sea cucumbers or sea urchins.
Embryonic origin of the cerebral hemispheres?
Forebrain
What is the embryonic origin of the cerebral hemispheres?
The embryonic origin of the cerebral hemispheres is from the neural ectoderm. The neural ectoderm is an area of tissue that forms in the center of the developing blastocyst.
What is a medulla What do forensic scientists use this for?
The medulla is the central portion of a hair strand. Forensic scientists use the medulla for hair analysis and comparison, as the medulla's characteristics can help identify the species of origin and potentially differentiate between individuals.
What is the most complex of all the system in the body?
its the embryonic origin of biological enzymes.
Why is Adductor magnus muscle considered as a hamstring muscle sometimes?
Due to its common embryonic origin and its innervation and action.
What is the embryonic origin of the skin?
The skin originates from the ectoderm layer of the embryonic germ cells. During development, the ectoderm gives rise to the epidermis (outer layer of the skin) and its appendages such as hair follicles, sweat glands, and nails.
What are the funtions of the medulla?
The medulla is the lower part of the brain stem. It includes areas such as the medial lemniscus, the pyramids, the inferior cerebellar peduncle and also has the hyperglossal nucleus and vestibular nuclei. The medial lemniscus consists of ascending axons carrying sensory information from the limbs to higher to higher centres in the brain. The Pyramids include descending motor fibres which start from the cerebral cortex and descend to the spinal cord. The inferior cerebellar peduncles carry information from muscles and joints to the cerebellum. The hyperglossal nucleus is the origin of the hyperglossal nerve and this is where nerve fibres lie. It innervated tongue muscles. And finally, the vestibular is where the vestibular nerve ends. Most of the nerve fibres bring in information about balance and equilibrium from the cerebellum. So basically, the medulla is a place in the brain where sensory and motor pathways come through and leave to either go up towards the brain or down to the spinal cord to integrate and coordinate movement.
What advantages do embryonic stem cell have over adult stem cells in medical research?
Human embryonic and adult stem cells each have advantages and disadvantages regarding potential use for cell-based regenerative therapies. ... Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin. Embryonic stem cells can be grown relatively easily in culture.

How does striated visceral muscles differ from striated cardiac muscles?
it has a different embryonic origin - it is neither cardiac nor skeletal muscle. it is often found in the head and neck.
Hormones secreted by derived from mesodermal embryonic origin tend to be in chemical nature?
Protein-based hormones. Examples include insulin, glucagon, and growth hormone.
