☺qoooooq and ramu5 help me☺....details note on Hypothalamus, thalamus and spinal cord...Needed quality answer,,only qooooq and ramu5 help me,,noone alse otherwise i will report

Answer 1

Hey dear !!

So here's u r answer !!

____________________________________________

➡ Hypothalamus :-

↪It is situated at the base of the brain and is composed of nervous tissue , the neurosecretary cells of the hypothalamus secrete several neurohormones called Releasing hormones (RH) and Inhibiting factors or hormones (IH or IF) .

↪This neurohormones are carried to the pituary gland to stimulate or inhibit the secretion of interior pituary hormones .

↪Hypothalamus also elaborates two neurohormones Oxytocin and vasopressin These are subsequently stored in posterior lobe of pituitary the well-known releasing and inhibitory factors of hypothalamus and response of pituary.

➡ Thalamus :-

↪It lies on the inferior side of the cerebrum and thus is visible in the ventral view of the brain .

↪It's roof is called epithalamus andt sides are called thalami and it's floor is termed hypothalamus .

↪It has a narrow cavity called third ventricle . Pituary is attached by a stalk to the region .

↪Thalamus is the structure in the middle of the brain . It is located between cerebral cortex and midbrain .

↪Hypothalamus has control centres for hunger , thirst , fattigue, body temperature , sweating , emotions .

↪It secrets neurohormones which regulate the situations of anterior lobe of pituitary .

➡ Spinal cord :-

↪Spinal cord is a cylindrical structure and is about 45 cm long .

↪It begins in continuation with the medulla oblongota of brain and extends downwards up too early part of lumbar region .

↪It then extends to the end of vertebral column as fibrous connective called filum terminale .

↪Internally the spinal cord possesses on narrow fluid filled cavity called Central Canal .

↪Spinal cord is enclosed in the vertebral column or backbone which protects it . Like brain spinal cord is too surrounded by many meninges .

↪Thirty one pairs of spinal nerves arise from the spinal cord . Spinal cord performs two important functions

↪It conducts sensory and motor impulses to and from the brain

↪It acts as a Centre for the reflex action .Thus it reduces brain's work .

HEYA!!
----------

✨HYPOTHALMUS✨
-----------------------------------------------------------------------------------------------------

➡It is a small portion of the human brain . It is Made up of very small and distinct nucleii and is present in the Nervous system of all vertebrates .

➡It is located at the base of the Brain , near the Pituitary Gland that is below the Thalmus .

➡It is a part of the Limbic System.

➡Its main functions are :

✨To release Hormones for control and coordination in the body .

✨Linking of the Nervous system with the Endocrine system ( through the Pituitary Gland ).

✨Plays major role in regulating body temperature.

✨It also controls Appetite .

➡It has three main regions that have different nuclei. They all perform vital function .

⭐When the Hypothalamus doesn't work properly , it is called Hypothalmic Dysfunction .

-----------------------------------------------------------------------------------------------------

✨THALMUS✨

➡It is a small structure within the Brain .

➡It is located above the Brain stem . It lies in between the cerebral cortex and the mid Brian . It is connected with nerves to both the membranes.It

➡The brain is composed of Ventricles. Thalmus lies in the third Ventricle .

➡Its main functions are ;-

✨Reguates sleep and alertness

✨Growth of Immune system .

✨It transfers sensory signals to cerebral cortex .

-----------------------------------------------------------------------------------------------------

✨SPINAL CORD✨

➡It is a long chord like structure that is encoded within the Vertebral Coloumn of our body .

➡It descends from the base of the Brain .

➡It is part of the Central Nervous System ( CNS)

➡It branches to form the Nerves that transfer the motor as well as sensory nerves from and to the brain .
