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.
The embryonic origin of all neural tissue?
neural plate
The embryonic origin of the diencephalonincluding the thalamus optic chiasma and hypothalamus?
forebrain
What is the most complex of all the system in the body?
its the embryonic origin of biological enzymes.

What is the origin of olivospinal tract?
It arises from lateral vestibular nuclei in the pons
Why is Adductor magnus muscle considered as a hamstring muscle sometimes?
Due to its common embryonic origin and its innervation and action.
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.
